Creaghorn, your suggestion makes logical sense, but would not work, I'm afraid.
Cause, you may have more than one kill, but both where seen by different people maybe.
Or, even worse: yesterday we got jumped at by those Nupe 17 again from Esc.86 - their leader,
ace Henri Joseph Marie Hay de Slade can't bear it, that I had shot him down once before.
So they didn't stop attacking us, until I had shot down FIVE of them.
Now I filled in five into the claim form. Erroneus. Okay, make four. Erroneus! I cut it back to three.
Erroneus! Only the first two where still seen by wings - after that I must have fought alone.
So, how should the program decide that?
