Night Bombing SBR. All HRs, NAs, Techs, and custom sculpt ideas welcome

  • '17 '16

    @Imperious:

    I don’t understand.

    Just make an example without all the 2/16 x34 XYZ thing.

    I think you mean: planes roll d6 count only damage 1-4, making 5 or 6 a miss.
    The ones that miss get a AA roll against them hitting at 1?

    Is that the idea?

    Yes it is.
    Sorry, I thought that the bold sentences were as near an example as possible.

    Another way to play Night Bombing could be as a 1 round preemptive regular attack against IC:
    Only bombers (StB and TcB) which miss are shot at by AAA @1.

    So, each StB and TcB get as many damage as they roll for succeeding:
    1 to 4 success (for 1 to 4 IPCs bombing damage), 5 and 6 miss.

    After, AAA @1 roll only against each StBs and TcBs which get 5 and 6.

    So, 1 StB and 1 TcB are Nightbombing: they roll a “5” and a “4”.
    StB missed.
    TcB gets 4 IPCs damage on IC.

    AA gun from IC gets a chance to roll against StB: a “2”, it is a miss.
    The StB survived the Night bombing along with the TcB.

    If AA gun have rolled “1” instead of the “2”, then the StB would have been destroyed.

    That’s the only way to reduced the AA gun hit ratio against bombers doing Night SBR within the actual A&A game mechanics.

  • Customizer

    For God’s sake it’s a simple idea. For frickin’ fun. As for the bombers intercepting it could easily be 86’d. In my defense damn near every German bomber has a night fighter variant in real, actual, historical, life. HBG has any number of custom sculpts that could be used as a night fighter possibly a tech or whatever hell suits your fancy. Night fighters could also be a custom National Advantage.

    As for wider appeal to/for the masses, IL’s idea of halving damage for night raids, sans the night fighters, is easy and would work fine.

    So, we can let aside the StB sculpt and unit as a Night Fighter.
    Instead, use a TcB (such as Mosquitos) or HBG custom sculpts that could be used as night fighter interceptor and escort.

    So, in both daylight SBR and night SBR, StB are attacking IC.

    In daylight, TcB cannot attack IC but can attack NB or AB.
    At night SBR, TcB can be used as escort for StB (turning back before AA fire on it) and as raider on IC (submitting to AA fire, same as StB).
    Is the last point OK for you?
    Or do you keep nightfighter (TcB) as Interceptor and escort only, and keeping StB as the sole unit to bombard IC?

    As I said earlier, the Imp Leader half damage (rounding up) night raid without interceptor is for historical junkie, not for player who want to win the game with optimal tactics, because it is too detrimental against bombers taking part in it with no interesting reward: daylight SBR will totally prevail in such HR.

    But the real Imp Leader (rounding down) night raid without interceptor is actually more powerful than the daily light SBR. It will be the end of OOB SBR as such, and Night raid will prevail:

    Does the idea is to make Night SBR a different and advantageous tactics with distinctive features over daylight SBR?

  • Customizer

    This idea is really not that complex. It’s an idea that has a historical basis no matter what scale or game we’re talking about. For the sake of argument let’s just ditch the interceptors and escorts. Keep the attack focused on ICs only. Reduce AA fire to half the casualties as well as halve the damage inflicted on ICs. the advantage to either side is half damage or casualties and adds another option to the game. Not really all that complex.

    As for custom units. I’m tired of making suggestions on this in regards to HRs. There are so many ways to go with these, from simple esthetics to making your own rules. Â

    Edit: It must also be specified that in a scenario where it was 1vs.1 STB vs. AA  an AA rolling a hit and halving the result then rounding down would mean the bomber would always break through AA fire.

    This could be avoided by rounding up or using a D12@1 for AA fire all rolls of one on a D12 die/dice hit with not halving mechanism. Additionally a sub-rule or exception could be made where a single bomber could be repulsed.

    Or night raids could only be performed with two or more bombers only.

    Or night raids could simply be repulsed rather than destroyed. This could possibly be further modified by allowing AA to fire at 2 or less. They wouldn’t destroy night raiders but they could repulse them with the advantage of a higher defense stat.

    Lastly, the original idea could be changed whereby the whole night raiding idea is changed altogether: Nighttime SBR is similar to regular SBR except there are no escorts or interceptors and only ICs may be targeted. Only AA fires just as normal. STBs that survive the AA barrage must roll their regular combat attack stat of 4@D6. If they score a hit they cause 2 damage points. This version of the rule negates interceptor and escorts risking only AA fire from the IC however they inflict much less damage.

    I’m unlocking this topic for the sake of anyone who wants to contribute their own ideas for SBRs at night. I’d suggest that anyone reading this read the entire thread and note the evolution of the thread from the original post. EVERYONE is encouraged to post. This thread is not intended to be a soap-box for myself or any one singular participant.

    Have Fun.

    Below, you find a complete statistical comparison between all HRs suggested lately.
    The OOB G40 SBR is the base of comparison at 100%.
    Formula:

    Avg damage done on IC  minus  avg IPC from StB casualty = IPCs damage/StB run   xxx%vs OOB SBR

    @toblerone77:

    What is so hard to understand?

    Three STBs make a night raid. The defender rolls three dice and scores 3 hits by a miracle.
    So 1.5 hits rounded up, it’s two hits, rounded down it’s one hit. The remaining attackers roll for damage and the total is halved to the nearest IPC worth of damage up or down.
    If some one were to use the HR their group could decide.

    Want simpler rolls for AA guns during a night raid? Easy use D12 dice and have them roll at 1. That equates .5 pips on a D6 die. Easy.

    You got it man!!!  :-o  I completely forgot about this possibility of using D12.

    I believe you already play with D12, so it won’t be difficult to introduce it in your game.
    Day and night AAA will be distinct this way:
    Day AAA, use 1 on D6 or “1” or “2” on D12.
    For an average casualty of 2/12 * -12 IPCs = - 2 IPCs/StB run.

    Night AAA, use “1” on D12.
    For an average casualty of 1/12 * -12 IPCs = - 1 IPC/StB run.

    One casualty roll is always better. And you get your half casualty average for Night Bombing.

    The last point remaining is on damage roll of 1 StB.
    Day time SBR:
    G40: D6+2 (avg 5.5) * 5/6 = 27.5 IPCs/6 =      4.583 IPCs/StB - 2 IPCs = 2.583 IPCs/run 100%
    1942.2: D6 (avg 3.5) * 5/6 = 17.5 IPCs/6 =      2.917 IPCs/StB - 2 IPCs = 0.917 IPCs/run 35.5%


    Night time SBR:
    D6 (avg 3.5) * 11/12 = 38.5 IPCs/12 =    3.208 IPCs/ StB  - 1 IPC = 2.208 IPCs/ run  85%

    (D6+2)/2 rounding up (avg 3) * 11/12 = 33 IPCs/12 = 2.750 IPCs/ StB -1 IPC = 1.75 IPCs/ run 68%

    (D6+2)/2 (avg 2.75) * 11/12 =  30.25/12 = 2.521 IPCs / StB - 1 IPC = 1.521 IPCs/ run 59%

    (D6+2)/2 rnd. down (avg 2.5) *11/12 = 27.5 IPCs/12 = 2.292 IPCs/StB-1 IPC= 1.292 IPCs/run 50%

    D3 (avg 2) * 11/12 = 22 IPCs/12 =          1.833 IPCs/ StB  - 1 IPC = 0.833 IPCs/ run  32%

    Last Tob77 version 4 out 6 doing 2 IPCs damage:
    4/6 * 2 IPCs * 5/6 = 40 IPCs/36 =           1.111 IPCs/StB - 2 IPCs = -0.889 IPCs/run - 34%

    AA gun hits halved rounded up version for 2 StBs:
    D3+1(avg 3)*11/36=33 IPCs/36=      +0.917 IPCs/ 2StB
    D3+1(avg 3)225/36=150 IPCs/36= +4.167 IPCs/ 2StB - 3.667= 1.417/2= 0.709 IPCs/ 1 StB run 27%
                                                                                or -1.834 IPCs/ 1 StB

    AA gun hits halved rounded down version for 2 StBs:
    D3+1(avg 3)*1/36=3 IPCs/36 =         +0.083 IPCs/2StBs
    D3+1(avg 3)235/36= 210 IPCs/36= +5.833 IPCs/2StBs -0.333= 5.583/2= 2.792 IPCs/1 StB run 108%
                                                                                 or -0.167 IPCs/ 1 StB

    1 StB against AAA repulse @2:
    D3+1 (avg 3) * 4/6 = 12 IPCs/6 =      2 IPCs/ StB   - 0 IPC = 2.00 IPCs/ run  77%

    Rolling damage first 1 to 4 IPCs, 5 or 6 is a miss and get under AA fire @1:
    1+2+3+4+0+0=10/6 IPCs =         + 1.67 IPCs - [(12 IPCs*2/36)= 4/6] .67 = 1 IPC/ run 39%

    Night time bombing played as Convoy disruption on 1-3 damage (4-6= 0), no AA fired:
    1+2+3+0+0+0=6/6=                     +1 IPC             - 0 IPC = 1 IPC damage/ run 39%

    @Baron:

    @SS:

    K I S S.

    Do you find this Night bombing SBR KISS or not?

    “Historical” light projector “search and spot” in the night sky:
    Each StB is spot on a 3 or less.

    Then roll to attack spotted StB with AA gun: on “1” roll a spotted StB is destroyed.
    (Work as the usual in-built AAA in IC.)

    All surviving StB bombard 1D6-1 damage against IC.

    If you want to have all these detection rolls and complicated rules in your HRs go ahead, God bless ya, I’m not saying you shouldn’t, but don’t be so condescending about my HR as if it were completely wrong and your is right just because you don’t like it.

    Do you see now that I wasn’t trying do criticize your first Night Bombing HR for the sake of the argument or for promoting my preference either?

    Just trying to see the consequences imply within a given set of rules and using the maths analysis tools I develop lately (while reading others posts on SBR) and getting a better grasp of it myself along this exchange on your thread.


    About your last Night time SBR, I think it is weird compared to all others (and not very attractive either):

    Last Tob77 version 4 out 6 doing 2 IPCs damage:
    4/6 * 2 IPCs * 5/6 = 40 IPCs/36 =     1.111 IPCs/StB - 2 IPCs = -0.889 IPCs/run - 34%

    Don’t you think?


    By the way, I really miss your idea on bombers having a special role as Night Fighters.

    It really adds something different and special to Night time SBR,
    and (to my own surprise: bombers being fighters?  :?) was depicting an historical fact.

    Maybe you can keep StB as interceptors if you chose 1 on D12 for AA fire, and 1D6 for damage: giving less than 85% efficiency vs OOB. Or, if you find it too much, keeping D3+1 at 68% vs OOB.

    Don’t forget that attacker have both choice: night or day SBR.
    Does many ICs will have both covers? Fgs and StBs for both kind of interceptions?


  • I think any solution must be contained in not more than 3 sentences…

    1. night bombing allows tactical or strategic bombers to make strategic bombing runs. They each roll their attack factor or less and damage equals what they roll ( bombers 4 or less, tactical 3 or less)
    2. no scrambling by either side
    3. AA guns roll normally

    2. no scrambling by either side
    3. AA guns roll normally

    Since there is no interception, it is easy to make calculations.
    Let me see…

    Night time StB 1-4 damage
    1+2+3+4+0+0=10/6 * 5/6 = 50/36 or 1.388 IPCs - (12*1/6=) 2 = - .612 IPC / StB run  -24%

    Night time TcB 1-3 damage
    1+2+3+0+0+0=6/6 * 5/6 = 30/36 or 0.833 IPC - (11*1/6=) 11/6 or 1.833 = -1 IPC / TcB run -39%


    Once calcs are done, I don’t think it will be a viable and interesting option for players.
    They will keep doing Day-time SBR (at 2.583 IPCs/ StB run).

    I think that it needs to be at least above zero to give an incentive to risk some Night bombing run.
    For example, the 1942.2 SBR without interceptor is a positive .917 IPC/ StB run.

    It could be simple as that:

    When playing G40 SBR, Night-time StB run is the basic 1942.2 SBR (regular AAA@1 and 1D6 damage).

    It will still be 35.5% vs OOB G40 SBR.

    There still be less chance of being shooted down than usual because there will be no interceptor defending.
    (So keeping the historical feel that Night time SBR are less dangerous.)


    You can also use this :

    Night time TcB damage: D6/2+1= 2-4
    2+2+3+3+4+4=18/6 or 3 * 5/6 = 15/6 or 2.5 IPCs -(11*1/6=) 11/6 or 1.833= 4/6 or .667 IPC/TcB run 26%

    TcB Night bombing (2-4) will be more accurate than StB (1-6) but still less destructive on the average.
    And I believe it is also historically accurate.

  • Customizer

    I’m just going to say something here. Excluding your math Baron. The whole point of this rule was to open up a way for SBR against ICs with a loose historical basis. The loose historical depiction of night bombing was to give the attacker a less risky SBR but the penalty was less risk=less reward.

    Given the basic concept, I think it is viable. I liked the idea of night fighters but thought it best to drop them. That’s my POV. An SBR that drops interceptors/escort could simulate this simply.

    Personally I like the thought of using a combination of D6 and D12 dice. When using a D12 system D6 dice aren’t necessary. I know this but I like D6 dice and will continue to use them. I also intend to use D12 dice for custom units and rules in the future and also have other ideas in the works.

    I encourage everyone to post as they like. Personally I like the idea of simply eliminating escorts and interceptors for night raids and reducing AA fire 1@D12. Damage totals are halved. That’s just what I like.

    Everyone else, carry on.

    About damage halved, you will use (1D6+2)/2 rounded up?
    D3+1 (avg 3) * 11/12 = 33 IPCs/12 =      2.750 IPCs/ StB   - 1 IPC = 1.75 IPCs/ run  68%

    So, TacB damage (if allowed) will be D6/2, since regular is D6 ?
    D3 (avg 2) * 11/12 = 22 IPCs/12 =          1.833 IPCs/ StB  - 1 IPC = 0.833 IPCs/ run  32%


    Ultimately, at a strength of 68% of OOB for StB Night-Bombing, this will be very attractive tactics I think.

    Much more than using regular AAA@1 and 1D6 damage (only 35.5% of OOB SBR).
    It will be almost two times more effective than using 1942.2 SBR as Night-bombing.

    And keeping a real half-casualties rate is much clearly depicting the protective effect of Night-bombing than 1942.2 SBR.

    Maybe it is still too much and can render OOB SBR obsolete unless attacker want to destroy some enemy’s Fighters.

    The base of comparison: was an average of 2.583 IPC/run is a rare situation when the defender have no Fg interceptor to give a better cover for his IC.

    A more usual and average situation is probably 1 StB doing SBR against 1 Fg interceptor.
    Or any 1 StB : 1 Fg ratio.
    (Because if either side can bring too much Fgs, there will be no SBR or no interception.
    For example, 1 StB:2 Fgs ratio begins to be  unappealing for the attacker:
    Damage: + 4.85  casualties: - 5.056 = - 0.206 IPCs damage/StB run)

    And it gives these results:
    Damage: + 5.487 IPCs/StB
    Casualties: - 3.672 =
    + 1.815 IPCs damage/StB run when 1:1

    1:1 intercepted SBR, 1.815 vs Night bombing (d3+1), avg 3 for 1.75 IPCs/StB run gives 96%, almost even!!!.

    1.815 vs (D6+2)/2, avg 2.75, for  1.521 IPCs/StB run, gives 84%

    1.815 vs (d6-1), avg 2.5, for 1.292 IPCs/StB run, gives 71%.

    1.815 vs (d3), avg 2, for 0.833 IPC/StB run, gives 46%.

    1.815 vs (1942.2 SBR AAA@1/6, D6), avg 3.5, for 0.917 IPC/StB run, gives 51%.

    I really think this other aspect should be considered since
    Night SBR has no interception and provides a way to always overcome any number of Fgs put to protect an IC.
    If the damage rate is too much, some players will find this frustrating being crippled by a fleet of Night StBs.

    In addition, historically speaking, Night Bombing was less dangerous but also clearly less accurate than day-time.
    (It seems that some  Day light raids have 5% vs 1% casualty for Night, 5 times less, but 1 Night bomber out of 3 was finding target in the worst situation, like foggy night…)

    So, what is the balance damage rate for an interesting but not too appealing either Night SBR?


    Here the calculations:

    OOB G1940: 1 StB A1 vs 1 Fg D1 doing interception

    StB roll /Fg roll / AAA roll

    116= 6/216 1 StB killed by Fg vs 1 Fg killed: 2.8%

    551= 25/216 StB killed by AAA: 11.6%
    555= 125/216 both survived: 57.8%

    69.4% * ((1+2) +(6+2) IPCs)/2= + 5.5 IPCs) = 3.817 IPCs
    16.7% killing Fg *+10 IPCs = + 1.67 IPC
    30.6% StB killed *-12 IPCs = - 3.672 IPCs

    Sum: 5.487 - 3.672 = + 1.815 IPCs damage/StB run


    OOB G1940: 1 StB A1 doing SBR against 2 intercepting Fgs D1

    StB roll / interceptors Fgs roll / AAA roll = odds   casualties

    1/611/366/6=  66/1296    1 StB killed by Fgs vs 1 Fg : 5.09%
    1/625/361/6 = 25/1296   1 StB killed by AAA vs 1 Fg : 1.93%
    1/625/365/6 = 125/1296  no casualty  vs 1 Fg : 9.65%

    5/611/366/6 = 330/1296    1 StB killed by Fgs vs no casualty : 25.46%
    5/625/361/6 = 125/1296    1 StB killed by AAA vs no casualty : 9.65%
    5/625/365/6 = 625/1296   no casualty at all : 48.22%

    I encourage everyone to post as they like. Personally I like the idea of simply eliminating escorts and interceptors for night raids and reducing AA fire 1@D12. Damage totals are halved.

    Since half-damage of OOB is D6+2/2= D3+1 which gives
    an average of 3 and a damage range of 2-4 IPCs on IC,
    there is another way of playing half-damage which is statistically the same but with different results for a single bombing damage:

    Rolling D6 but ignores all “6”.
    This give the same average of 3 (1+2+3+4+5= 15/5=3) but provides a wider range of damage to IC: 1 to 5 IPCs.

    So, you can choose one over the other according to which historical aspect of Night bombing you prefer:

    • First method, Night SBR quite ineffective on inflicting heavy damage (a real half max dmg: 8 vs 4).

    • Second method, Night SBR quite unable to reach their designated target, lesser than half minimum damage (3 vs 1) but sometimes can get lucky, getting a high dmg of 5 IPCs.

    Or maybe, third method, what you meant above was simply to roll for each StB 1D6+2, then making the sums and, after, dividing it by two rounding up or down. According to your preference.
    This will imply an average of 3+4+5+6+7+8= 33 / 6= 5.5 / 2=  2.75 IPCs per run.

    Rounding down damage: 3=1, 4=2, 5=2, 6=3, 7=3 , 8=4 sums: 15 / 6 = 2.5 IPCs per run.
    Rounding up damage: 3=2, 4=2, 5=3, 6=3, 7=4, 8=4 sums: 18/6 = 3 IPCs per run.


    So, considering these 3 methods,
    what will be yours Toblerone77?

    And if you choose the third one,
    will you**, in game, keep track of .5 IPC (2.75 avg)**, 84% of 1:1 StB vs Fg or 59% of StB vs AAA only,
    or rounding down (2.5 avg), 71% of 1:1 StB vs Fg or 50% of StB vs AAA only,
    or rounding up (3 avg), 96% of 1:1 StB vs Fg or 68% of StB vs AAA only?


    For easier view of both references at 100%:
    G40 1 StB vs 1 Fg, and AAA: D6+2, (avg 5.5), + 1.815 IPCs/StB run
    G40 1 StB vs AAA only: D6+2, (avg 5.5), + 2.583 IPCs/StB run.

    @toblerone77:

    I’m just going to say something here. Excluding your math Baron. The whole point of this rule was to open up a way for SBR against ICs with a loose historical basis. The loose historical depiction of night bombing was to give the attacker a less risky SBR but the penalty was less risk=less reward.

    Given the basic concept, I think it is viable. I liked the idea of night fighters but thought it best to drop them. That’s my POV. An SBR that drops interceptors/escort could simulate this simply.

    I encourage everyone to post as they like. Personally I like the idea of simply eliminating escorts and interceptors for night raids and reducing AA fire 1@D12. Damage totals are halved. That’s just what I like.

    Everyone else, carry on.

    Hi Toblerone77,
    I don’t know if you play 1942 second edition, but within the optional rule for SBR escort and interception it becomes viable to have such thing as StB playing a role as Night-fighter, because the odds are clearly different from G40 during the regular SBR with escort: all Fgs and StB A1 first strike, while Fg D2.

    All you have to do to implement a 1942.2 Night bombing & Night Fighter HR is this when playing with escort and interception optional rule:

    • Day SBR damage on IC becomes 1D6+2/StB, instead of just D6.

    • During 1942.2 Night SBR, the damage becomes D6-1/StB (or D6+2 halved rounding down, if you prefer).

    • In addition, all attacking StBs and defending StB Night-fighters roll a regular A/D@1, same as G40 SBR escort and interception rule.

    • The AAA fire @1 in both cases, Day or Night SBRs.

    These 2 things will make all the basics 1:1, StB vs Fg/StB Night Fg, balance.

    Day SBR:
    StB vs AAA, damage + 4.583 - casualty 2.0 = +2.583 IPC damage/StB
    StB vs Fg+AAA,  damage + 4.977 - casualty 4.777 = + 0.2 IPC damage/StB

    Night SBR:
    StB vs AAA, damage +2.083 - casualty 2.0 = +.083 IPC damage/StB
    StB vs StB NF+AAA, damage +3.736 - casualty 3.667 = + 0.069 IPCs damage/StB run


    So, Night SBR is better when there is more than 1 Fg defending an IC, and it is still an even match for both sides (near 0 IPC) to throw 1 StB against a StB NightF.

    But, if there is only 1 Fg on the IC, the Day SBR is still positively better (.2 vs .069).

    In addition, there is less StB and money in 1942.2 compared to G40, so there is lesser chance that StBs presence will forbids any Night SBR.

    To summarize the viable SBR tactics with this 1942.2 HR:

    1. No Fgs on IC, go for Day-SBR
    2. 2 or more Fgs on IC, go for Night-SBR unless there is more than 1 Night-Fg for 1 StB raider.
    3. Keeping a 1 Fg + (1 StB :1 Fg) advantage for Day bombing is better.
    4. Or staying within the 1 StB and 1 Fg vs 2 Fgs is the lower limit, it is still viable around 0.00 IPC/StB run.
      So, going 1:1 vs Day or Night is almost the same risks involved, but with less damage & casualty in Night SBR.

    What do you think of this?

    Now, Night Bombing can be viable in both games.

    Here is the calculation basis for this 1942.2 Night bombing with Night Fgs House Rule:

    OOB 1942.2: 1 StB doing SBR without interceptor
    5/6 StB survived * 3.5 IPCs = 2.9 IPCs
    1/6 StB killed *12 IPCs = -2 IPCs
    Sum: 2.9 - 2 = +.9 IPC damage/StB

    OOB 1942.2 SBR with D6 damage:
    1 StB A1 first strike against 1 intercepting Fg D2

    StB roll (D6)/Fg roll / AAA roll

    161= 6/216 1 StB killed by AAA vs 1 Fg killed: 2.78%
    165= 30/216 no casualty vs 1 Fg killed: 13.89%

    526= 60/216 StB killed by Fg: 27.78%
    541= 20/216 StB killed by AAA: 9.25%
    545= 100/216 both survived: 46.3%

    Results with :
    60.19% * ((1+6) IPCs)/2= +3.5 IPCs) = 2.107 IPCs
    16.67% killing Fg *+10 IPC = + 1.667 IPC
    39.81% StB killed *-12 IPCs = - 4.777 IPCs

    Sum: 3.774 - 4.777 = - 1.0 IPC damage/StB


    1942.2 HR damage D6+2 : 1 StB doing SBR without interceptor
    5/6 StB survived * 5.5 IPCs = 4.583 IPCs
    1/6 StB killed *12 IPCs = -2 IPCs
    Sum: 4.583 - 2.0 = +2.583 IPC damage/StB

    1942.2 SBR HR with D6+2 damage:
    1 StB A1 first strike against 1 intercepting Fg D2

    StB roll (D6)/Fg roll / AAA roll

    161= 6/216 1 StB killed by AAA vs 1 Fg killed: 2.78%
    165= 30/216 no casualty vs 1 Fg killed: 13.89%

    526= 60/216 StB killed by Fg: 27.78%
    541= 20/216 StB killed by AAA: 9.25%

    Results with :
    60.19% * ((1+2) + (6+2) IPCs)/2= +5.5 IPCs) = 3.31 IPCs

    39.81% StB killed *-12 IPCs = - 4.777 IPCs
    Sum: 4.977 - 4.777 = + 0.2 IPC damage/StB
