G40.2 1942.2 Formula to balance cost and combat points for customized units


  • @Imperious:

    The Larrymaxx formula since it takes into account the subs , combined arms , and 2 hit BB makes it superiour by far.

    All hail the Larrymaxx formula!

    Could it be ???    Naw !  :?

    Hail Hail Hail Hail Hail Hail Hail Hail Hail


  • Hello Baron, now with your formula I see, why you suggested 15IPC instead of 14IPC for our cruiser A3 D3 2 hits.
    It brings it closer to the rate of destroyers. (15IPC = 1,26)

    Hello Baron, now with your formula I see, why you suggested 15IPC instead of 14IPC for our cruiser A3 D3 2 hits.
    It brings it closer to the rate of destroyers. (15IPC = 1,26)

    8-)

    Now you said it, I saw it too.
    This might help make comparative analysis between various units OOB and customized.

    It is much easier to compare two numbers than rolling many simulations on an AACalc.
    Things remains relative to the OOB Destroyer.

    For instance, the 2 hits Cruiser idea help me bring it into a balanced fit with a G40 Redesign (Philadelphia Experiment, cost structure 5-6-9-12-15-18) roster:
    Destroyer A2 D2 C6, 1 hit.
    Offence & defence factor:
    36*2/6^2 = 2

    So I can use a Cruiser A3 D3 C12, 2 hits
    Offence & defence factor:
    36*3/12^2 * 2.618034= 1.96

    I deliberately choose a lower 5-6-9-12-15-18 cost structure for warships.
    I might have keep Cruiser A3 D3 C9, 1 hit
    Offence & defence factor:
    36*3/9^2 = 1.33

    But it was so weak compared to Destroyer that I preferred this 2 hits Cruiser.

    This formula is not that bad. It doesn’t solve everything but help make some choices.

    For instance, I have a Fighter in this roster which is A2 D2 M4 C6, 1 hit which always target enemy’s plane first, then AAA, then casualty selection as usual.
    Based on the formula, it the same as Destroyer.
    Offence & defence factor:
    36*2/6^2 = 2

    I can say that this ability maybe somewhat similar to the Anti-Sub capacity of DD.
    Maybe, maybe not.
    All that the formula reveals is that Tank are better for the cost and DD (1.125) vs Fg (Off 1.08 / Def 1.44) in OOB are quite similar.
    So this seems correct that Fg in this Experiment get a similar combat factor compared to Destroyer as the case OOB.

    Now, if I look at the Tactical Bomber A3 D2 M4 C7, 1 hit of this experiment…
    Offense factor:
    36*(3/7^2) = 2.20
    Defense factor:
    36*(2/7^2) = 1.47

    It is a bit better on Offense and weaker on defense. Now, you can judge if it can compare with OOB for Fg vs TcB analysis.

    All hail the Larrymaxx formula!

    It is Baron-Larrymarx formula,

    Larrymarx breaks the Vann code (which Vann still courteously provided in the player’s help while we were working at it),
    I standardized number in reference to Tank 3 and expanded the formula and basis to include other cases like 1942.2 Full Carrier, 2 hits or 3 hits warships and combined arms.
    Without the basic code, I would not have been able to push forward, hence the Larrymarx named.

    @Dauvio:

    It came to my attention that one of my formulas are already out there that I discovered 30 years ago.
    http://www.axisandallies.org/forums/index.php?action=profile;u=185969 has also discovered the formula P^2*N=S
    And just for fun you can try these formulas also. S/P^2=N. √(S/N)=P
    P=POINTS
    N=NUMBER OF UNITS
    S=STRENGTH OF ONE KIND OF UNITS IN A TERRITORY
    This formula should replace the punch formula. It is much better then the punch formula.

    Now the next formula is (P100)/(C^26)=S
    P=POINTS
    C=COST
    S=STRENGTH OF THE UNIT BASED ON COST

    With this formula you can also price units according to their strength. √((P100)/(S6))=C
    This formula is for points. (S*(C^2*6))/100=P

    For better results for some of these formulas, have all your units cost ten times then what they are. These are some of the VANN FORMULAS I came up 30 years ago.

    If you have any questions about these formulas, please ask.

    Here is the final numbers missing for G40 Carriers, there is probably a small difference compared to 50%-50% AACalc for defense because defense points are lost that way for 2 Fgs: 0,2,6,10 /2 = 0, 1, 3, 5 and not 0, 0, 3, 5 as I made in this formula.

    G40 Carrier A0 D2 C16, 2 hits
    Offense factor:
    36*[0/ (16^2)] * 2.618034 = 0
    Defense factor:
    36*[2/ (16^2)] * 2.618034 = 0.736

    G40 Carrier A0 D2 C16, 2 hits with 2 Fgs A6 D8 C20, 2 hits
    Offense factor:
       6/2  C36/2   2 additionnals hit/2
    36*[3/ (18^2)] * 2.618034 = 0.873

    Defense factor:
       10/2  C36/2  2 additionnals hit/2
    36*[5/ (18^2)] * 2.618034 = 1.454

    10/4  C36/4  1 additionnal hit considered as whole unit
    36*[2.5/ (9^2)]  = 1.111
    Until further investigation, I believe this average is better: (1.454+1.111)/2= 1.2825

    G40 Carrier A0 D2 C16, 2 hits with 1 Fg & 1 TcB A7 D7 C21, 2 hits
    Offense factor :
        7/2  C37/2   2 additionnals hit/2
    36*[3.5/ (18.5^2)] * 2.618034 = 0.964

    Defense factor:
        9/2  C37/2  2 additionnals hit/2
    36*[4.5/ (18.5^2)] * 2.618034 = 1.239

    9/4  C37/4  1 additionnal hit considered as whole unit
    36*[2.25/ (9.25^2)]  = 0.947
    Until further investigation, I believe this average is better: (1.239+0.947)/2= 1.093

    G40 Carrier A0 D2 C16, 2 hits with 2 TcBs A6 D6 C22, 2 hits
    Offense factor :
        6/2  C38/2   2 additionnals hit/2
    36*[3/ (19^2)] * 2.618034 = 0.783

    Defense factor:
        8/2  C38/2  2 additionnals hit/2
    36*[4/ (19^2)] * 2.618034 = 1.044

    8/4  C38/4  1 additionnal hit considered as whole unit
    36*[2/ (9.5^2)]  = 0.798
    Until further investigation, I believe this average is better: (1.044+0.798)/2= 0.921


  • Ok so I’m confused how am I supposed to apply the Vann-Baron-LArrynx formula? What do I do with the 1.454 number? And where is the derivation  for the formula? Or is it just made-up?


  • Ok i understand it but I don’t get how you got your 1.61 factor for the baron formula with hits.

  • '17 '16

    @Genghis:

    Ok i understand it but I don’t get how you got your 1.61 factor for the baron formula with hits.

    I was lucky on that one.
    I compared on AACalc similar Attack 3 Defense 3 with 1 hit vs A3 D3 2 hits.
    Knowing also that a A3 D3, 2 hits have a similar power 50-50% with A4 D4, 1 hit (was able to calculate).
    When I compared these two numbers, it was around 2.60… times greater than off def factor of A3 D3 1 hit.
    So, in my POV, it was close to 1+ golden number.

    I made an educated guess for the formula, and AACalc confirmed a few variations with A2 D2, 2 hits A3 D3, 2 hits and A4 D4 2 hits. It gave me near 50-50 each time. So it was OK.
    The next step was to try AACalc with a 3 hits against Fg 1 hit, give me 50%-50% and it works.

    So, maybe this formula will no work for 4 hits units but I don’t see the relevance of creating such units for A&A.

    …* {1+[(nb hit -1)/1*1.618034]}

    If 1 hit, it simply gives …* {1 + 0}
    1 +[(1 -1)/1*1.618034]

    If 2 hits, it gives … * 2.618034   {1 + 1.618034}

    • {1 + (2-1) *1.618034}

    If 3 hits, it gives … * 4.236068   {1 + 3.236068}

    • {1 + (3-1) *1.618034}

    @Genghis:

    The ability  to tip carriers and BBs neuters the submarine first strike ability (So no need for DDs) and I have yet to play a game where a sub first strike actually worked (i think it happened once). And most of the time you don’t want to attack with air force as well because then his fighters can defend at 4 and hit your planes and you arent allowed to use subs as casualties. Meaning it’s most of the time beneficial to not put a DD in your fleet, just spam loaded carriers.

    Only Fg+TcB stack seems to rivalize with G40 Full Carrier. Carrier were stronger so you can buy defenseless TPs.  Otherwise, 2 big defensive stacks of Carrier cannot break the ties going offense unless willing to lose units for greater purpose.

    I agree with you about this Submarine with no surprise strike.
    So I suggested a second different variant with 2 hits Cruiser and 3 hits BB in G40 Redesign.
    Subs is cheaper and always roll surprise. And in regular combat planes can still hit Sub without DD.
    But all ships cost are modified…

    But, you makes me wonder about the impact of 2 hits Cruiser on Submarine, even at 5 IPCs the Surprise strike is still nerfed …

    The cost structure put Carrier at 15 and make it less optimal, even with 3 Fgs on board.

    Anti-aircraft Artillery
    A0 D1* M1 C3, 1 hit,

    • @1 vs up to 3 planes, 1 roll per plane max, each combat round.
      It is not preemptive but a regular roll.
      When fighting against 1 aircraft:
      Defense factor:
      36*(1/3^2) = 4.00
      When fighting against 2 aircrafts:
      36*(2/3^2) = 8.00
      When fighting against 3 aircrafts:
      36*(3/3^2) = 12.00

    AAA (12.00) is stronger than Infantry (8.00) when defending against 3 planes but more AAA cannot hit the same unit, it has no offense value and don’t have the versatility of Fighter.
    In fact, this formula cannot consider multiple hits from a single unit.

    Now I can compare the Strength of both Subs:

    OOB
    Submarine A2 D1 C6
    Offense:
    36*(2/6^2) = 2
    36*(3/6^2) = surprise strike 3.00
    Defense:
    36*(1/6^2) = 1
    36*(1.33/6^2) = surprise strike 1.33

    Submarine A2fs D1fs C5
    Offense:
    36*(3/5^2) = surprise strike 4.32
    Defense:
    36*(1.33/5^2) = surprise strike 1.92

    Compared to Destroyer, it remains clear that you will not use Subs as fodder on offence, the First strike will be helpful.
    Also, on defense, you almost get a similar loss per cost, it might be a difficult decision whether submerging Sub for later or using  it as fodder.

    How did you get the factor 1.618034 for double haul BB??? I got a factor 1.6. I used the battlecalc I had 800 bombers attack 500 battleships.

  • '17 '16

    In all my simulations, it was not exactly a 1.6 factor. As far as I remember, always slightly above.

    Did you try it with 3 hits and 1.6 factor in a formula like:
    …* {1 + (3-1) *1.6}
    To see if you get nearer or farther than mine.

    The golden number have a few properties when making it square.

    I will try to see if I can retrieve what simulations I exactly done.

    This will help:

    @SS:

    500 Battleships ? Must be nice !

    Yeahh, totally not realistic!!!
    But when crunching numbers and trying to get randomness out of the way, the higher the number on AACalc the better you get an accurate average.

    Basically, 8 bombers (or damaged BBs) are near even with 5 battleships.
    In punch formula: 8 A4, 1 hit vs 5 A4, 2 hits are about 50-50% odds of survival.
    As you can see, even with 10 000x battles, odds varies with low numbers:
    Sim 1: A. survives: 49.5% D. survives: 44.1% No one survives: 6.4%
    Sim 2: A. survives: 48.3% D. survives: 45.4% No one survives: 6.3%
    Sim 3: A. survives: 49.5% D. survives: 44% No one survives: 6.5%
    Sim 4: A. survives: 49.1% D. survives: 44.1% No one survives: 6.7%

    @Dauvio:

    @Baron:

    @Genghis:

    Ok i understand it but I don’t get how you got your 1.61 factor for the baron formula with hits.

    I was lucky on that one.
    I compared on AACalc similar Attack 3 Defense 3 with 1 hit vs A3 D3 2 hits.
    Knowing also that a A3 D3, 2 hits have a similar power 50-50% with A4 D4, 1 hit (was able to calculate).
    When I compared these two numbers, it was around 2.60… times greater than off def factor of A3 D3 1 hit.
    So, in my POV, it was close to 1+ golden number.

    I made an educated guess for the formula, and AACalc confirmed a few variations with A2 D2, 2 hits A3 D3, 2 hits and A4 D4 2 hits. It gave me near 50-50 each time. So it was OK.
    The next step was to try AACalc with a 3 hits against Fg 1 hit, give me 50%-50% and it works.

    So, maybe this formula will no work for 4 hits units but I don’t see the relevance of creating such units for A&A.

    …* {1+[(nb hit -1)/1*1.618034]}

    If 1 hit, it simply gives …* {1 + 0}
    1 +[(1 -1)/1*1.618034]

    If 2 hits, it gives … * 2.618034   {1 + 1.618034}

    • {1 + (2-1) *1.618034}

    If 3 hits, it gives … * 4.236068   {1 + 3.236068}

    • {1 + (3-1) *1.618034}

    HTH

    How did you get the factor 1.618034 for double haul BB??? I got a factor 1.6. I used the battlecalc I had 800 bombers attack 500 battleships.

    101 BBs A4 D4, 2 hits vs 80 BBs A4 D4, 3 hits, near 50-50% odds,

    /40 =  20.5 dmgd BBs A4 D4, 1 hit vs 10 BBs A4 D4, 3 hits,

    So such 3 hits BBs should cost 20.5 IPCs and will be even with a Fg D4 C10 which is known at strength factor1.44

    36*4/20.5^2 * {1 + (3-1) 1.618034} = 1.45
     144/420.25  * 4.236068 = 1.4515
    OR
    36
    4/20.5^2 * {1 + (3-1) *1.6} = 1.44
      144/420.25  * 4.2 = 1.4391

    800 dmgd BBs A4 D4, 1 hit vs 500 BBs A4 D4, 2 hits, near 50-50% odds,
    /50 = 16 dmgd BBs A4 D4, 1 hit vs 10 BBs A4 D4, 2 hits,

    So, such 2 hits BBs should cost 16 IPCs and will be even with a Fg D4 C10 which is known at strength factor1.44

    Battleship A4 D4 C16, 2 hits
    Offense & Defense factor:
    36* 4 / (16^2) * 2.618034 = 1.4726
    OR
    36* 4 / (16^2) * 2.6 = 1.4625
    This last one is nearer.

    187 Cruiser A3 D3, 1 hit vs 100 BBs A4 D4, 2 hits, near 50-50% odds,
    /10 = 18.7 Cruiser A3 D3, 1 hit vs 10 BBs A4 D4, 2 hits,

    So, such 2 hits BBs should cost 18.7 IPCs and will be even with a Fg A3 C10 which is well known at strength factor1.08

    Battleship A4 D4 C16, 2 hits
    Offense & Defense factor:
    36* 4 / (18.7^2) * 2.618034 = 1.0781
    OR
    36* 4 / (18.7^2) * 2.6 = 1.0707

    737 Destroyers A2 D2, 1 hit vs 320 BBs A4 D4, 2 hits, near 50-50% odds,
    /40 = 18.425 Destroyers A2 D2, 1 hit vs 10 BBs A4 D4, 2 hits,

    So, such 2 hits BBs should cost 18.425 IPCs and will be even with a Destroyers A2 D2 C8 which is well known at strength factor1.125

    Battleship A4 D4 C18, 2 hits
    Offense & Defense factor:
    36* 4 / (18.425^2) * 2.618034 = 1.1105
    OR
    36* 4 / (18.425^2) * 2.6 = 1.1029

    466 Carrier A1, 1 hit vs 140 BBs A4 D4, 2 hits, near 50-50% odds,
    /10 = 46.6 Carrier A1, 1 hit vs 14 BBs A4 D4, 2 hits,
    So, such 2 hits BBs should cost 46.6 IPCs and will be even with a Carrier A1 C14 which is well known at strength factor0.18

    36* 4 / (46.6^2) * 2.618034 = 0.1736
    OR
    36* 4 / (46.6^2) * 2.6 = 0.1724

    So, I cannot tell from these various AACalc results which number is the accurate multiplier.
    Sometimes 1.6 seems nearest the point, while other times it is 1.618034.
    From an empirical POV and F-2-F, it can be easier to simply said 1.6 but from a derivative equation, which I don’t know, maybe it is PHI or golden number the correct multipler in this equation.

    If we try with this other equation.

    Metapower = units^2 * power

    N1 is nb of 1 hit units
    N2 is nb of 2 hits units
    (N1+ N2*1.618034)^2 * avg power [total power/(N1+N2 units)] = Metapower

    466 Carrier A1, 1 hit vs 140 BBs A4 D4, 2 hits, near 50-50% odds,
    466^21 = 217 156
    (140
    1.618034)^24= 205 253.9
    (140
    1.6)^2*4=200 704

    737 Destroyers A2 D2, 1 hit vs 320 BBs A4 D4, 2 hits, near 50-50% odds,
    737^22 = 1 086 338
    (320
    1.618034)^24= 1 072 346.74
    (320
    1.6)^2*4=1 048 576

    187 Cruiser A3 D3, 1 hit vs 100 BBs A4 D4, 2 hits, near 50-50% odds,
    187^23 = 104 907
    (100
    1.618034)^24= 104 721.361
    (100
    1.6)^2*4=102 400

    800 dmgd BBs A4 D4, 1 hit vs 500 BBs A4 D4, 2 hits, near 50-50% odds,
    800^24 = 2 560 000
    (500
    1.618034)^24= 2 618 034.025
    (500
    1.6)^2*4=2 560 000

    819 dmgd BBs A4 D4, 1 hit vs 400 BBs A4 D4, 3 hits, near 50-50% odds,
    819^24 = 2 683 044
    (400
    2.618034)^24= 6 702 167.1
    (400
    2.6)^2*4=4 326 400
    Here, the formula does not work for 3 hits units.

    Based on this Stack formula, I rather believe *1.618034, is a better multiplier to get equations results as similar as possible.
    Also, it seems to work better when compared to @1, @2 and @3.

    However, the only case where the formula is exactly even is the one you bring for A4 1 hit vs D4, 2 hits.
    800 dmgd BBs A4 D4, 1 hit vs 500 BBs A4 D4, 2 hits, near 50-50% odds,
    800^24 = 2 560 000
    (500
    1.618034)^24= 2 618 034.025
    (500
    1.6)^2*4=2 560 000

    HTH

    What battlecalc did you used for the for the different strength units??? The A&A battlecalc only calculates battleships.

  • '17 '16

    I used Transports and put TPs first in order of casualty.
    So it worked like a 2 hits unit for Carrier A1 D2 or Cruiser A3 D3, and a 3 hits unit if paired with 1 Battleship.
    If I want to recreate a G40 Carrier on offence, I put 2 TPs as similar to 1 Carrier.

    The on going discussion:
    http://www.axisandallies.org/forums/index.php?topic=40520.msg1693864#msg1693864
    on Transport with defense roll makes me wonder about actual combat strength of Classic Transport and an escorted TP:

    Transport and Destroyer A2 D2 C15, 1 hit
    Offense & Defense factor:
    36*(2/15^2) = 0.32

    Transport and Cruiser A3 D3 C19, 1 hit
    Offense & Defense factor:
    36*(3/19^2) = 0.30

    Classic Transport A0 D1 C8, 1 hit
    Defense factor:
    36*(1/8^2) = 0.5625

    I revised the opening post.
    As comparison points, a Fighter A3 D4 C10 off/def is 1.08 / 1.44

    Destroyer A2 D2 C8, 1 hit
    Offense & Defense factor:
    36*(2/8^2) = 1.125

    Submarine A2 D1 C6
    Offense:
    36*(2/6^2) = 2.00
    36*(3/6^2) = surprise strike 3.00
    Defense:
    36*(1/6^2) = 1.00
    36*(1.33/6^2) = surprise strike 1.33

    You need to send 2 Destroyers to get a similar defense value with Classic Transport strength 0.5625:
    Transport and 2 Destroyers A4 D4 C23, 2 hits
    Offense & Defense factor:
    36*(2/11.5^2) = 0.544

    Or make defenseless Transport a 4 IPCs unit:
    Transport and Destroyer A2 D2 C12, 1 hit
    Offense & Defense factor:
    36*(2/12^2) = 0.50

    Now, if you want to introduce a Classic TP with the same strength of actual DD+TP combo 0.32:
    You need to make TP cost 10,5 IPCs:
    Classic Transport A0 D1 C10, 1 hit
    Defense factor:
    36*(1/10^2) = 0.36

    At 11 IPCs, it would be 0.30 though.

    Transport defending A0 D1 would be interesting at a clean 10 IPCs.
