Sure I understand, perhaps could you had rate of turn (important test in the beginning of the war, ie test Spitv/s Me109) and acceleration in descent, just to avoid a fighter at 6 (test between USN and Zero) and at the end the amount of bullets in Kg and in Kj per minute just to know if I choose a Rata or a Corsair (bad example, I know!)
I remember there is a soft to compare the Il2 A/C. I don't know if it is efficient, according to me, graphs are more realistic, even if everybody can not all understand.
perhaps you have to translate in words what is in mathematic courbs, but it will take you more time!!
See you
