Well, thanx all for the explanations and comments. I do see what the differences are in impact of the different statistics. Wonder if there should be some kind of weighting as some point to reflect total combat time. By that I mean (as just one example) someone who flies 20 sorties makes 12 kills to 4 deaths, against someone that does 120 sorties and makes makes 60 kills and 30 deaths. The K/D ratio and other percentages favor the 20 sortie guy, but has he flown enough to be moderately reflective of skill and a higher score. Can't say I know where the weighting should kick in or how it works, but I do believe there needs to be a balancing based on overall risk.
Just a wild idea, no big thing.
Trivia question: do you think I'm player #1 or #2.

Thanx again all.
