Cool, I have no idea how to do that! But, doesn't the assumptions look a bit off? Surely the Ties would spend focus offensively even only 1 eye to hit (since only delta is shooting afterwards, and at this time it should be clear who delta is shooting anyway, so at least all but that guy shoud just spend away). And why would the Ties attack the delta first?
They shoot the delta first to try to take it off the board before it can shoot.
Its pribably also a faulty assumptioncthat all of the fighters will be at the same range. Theres decent odds theyll be split across 2 range bands.
