The score at best would be very fuzzy.
I can now figure out how many pilots we started with at T+0 and how were still in the arena at T+43 and flying. Although some possible error there since have to determine who is still flying versus possibly gunning.
Now as for the people gone at T+43 I don't know who exactly just that x of this squad is not present and y of the same squad still is. So all I really know is they are gone .. which could be killed, ditched, crashed, landing back at the base and deplaned do to battle damage, or dumped.
I can look at the battle plans of each CiC to figure out what squad was flying what but that number of pilots gone at the T+43 mark is the issue. At best it would be fuzzy math to count everyone gone as a loss.
