On SBR numbers, here is the difference:
Both seems to have the same _Break even poin_t compared to generous OOB G40 SBR: near 0.5 StB/Fg.
This simply means that 1 StB against 2 Fighters can be launched and odds of making damage will be around zero.
Both attacker and defender will take similar damage, if IC can absorb hit damage and is not near Maxed out.
So, on that point there is no difference. It will favour attacker the same as OOB SBR.
Now, about FIT (Fighter Interception Threshold), there is none when bomber have A0, you can always launch Fighters against infinite number of bombers, there is no cap.
It is always beneficial somehow to intercept.
However, with StB A1 and Fg A2 D2, it is better for defender when there is 3 bombers A1 and more against only 2 Fgs D2, to not intercept.
There is too much risk or said otherwise, AAA will give more damage on attacker than you will received.
So, stay on the ground if there is 2 StBs A1 for 1 Fg D2. (Not so rare occurrence.)
That is the main difference and it changes SBR dynamics radically without changing the general odds of making more damage than receiving.
IDK if any of those which prefer StB A1 vs Fg A2 D2 can accept to try both SBR.
And tell us which one they prefer.
I’m almost certain than for a real play-test, Barney can accept to modify StB and Fg dogfight values in a Triple A G40 map.
It is the only change same D6 damage in both case.
That way, we can get your first hand impressions on each.
Would you like one, YG or Ichabod?
Break even ratio:
OOB G40 SBR StB A1 D6+2 vs Fg D1: 10/19= 0.526 StB/Fg
Cost 5 D6 damage: 16 StBs A1 vs 31 Fgs D2, 16/31= 0.516 StB/Fg
Fighter Interception Threshold (FIT)
G40 OOB: from 1.55 StB/Fg and less
Cost 5: near 6 StBs vs 4 Fgs= from 1.5 StB/Fg and less
Break even point C5, 1D6 damage: near 1 StB A0 vs 2 Fgs D1 : 0.5 StB/Fg
1 StB vs 2 Fgs : + 2.025 - 2.106 = -0.081 IPCs
12 StB vs 23 Fgs: exactly 0.522 StB/Fg
No FIT (Fighter Interception Threshold), always beneficial to Intercept.
