Yes, it is a great prob and it is clear that much parameters must be taken in account, surely more as i am able to do.... so, i test much and more with a set of "natural ennemies"......
Clearly, no interest to test 0.50 on IL2....... but, i had two plane sets like pacific (zéro, ki61, betty, ki84 and so on) and one for western front (me109, fw, ju88....) and i try to compare my datas and values with ww2 guncams..... and...... result is not so far at them.......
For breda, i used spit, hurri, tomahawks and I16, IL2, lagg3......
I have not modified DM of the planes, because it is not simple and actually too complex for me..... and i know that we can see P51 chasing IL2 on HL but, no interest for me .
My work is surely not perfect, far of that, but it is the best i can do.... i don't think that Oleg can be interested by my work.....
he has another things in sight, and don't care, IMHO on weaponry prob in IL2....
All my work is transparent for those that want to know what i do....
Fianlly, my best test is when testers give me an opinion of what they saw in game, comparated to what they saw in documents...... and when they find no great difference....
