now that's just silly. see, we got into this mess when they started allowing multi-breakdowns. I'm beginning to miss 1E's simple breakdown!
split a FAP once and be done!
from the way i read the rulebook and fleet list for 2e, it is simple, i did't see any mention
for example you have a battle point that you split down to 4 skirmish points and then use 2 skirmish points to buy a raid ship.
you either go for 1 point buys x ships or break it down to 1X>2x>1x2Y>etc
not 1 battle > 4 skir >2 raid then back to what ever
