How are you conducting this survey? ~36 in just two months seems way low. I easily make that in less than 2-3 hours of playing. Granted I fly a 38G and 38J and always try to kill the 5eny birds first but 36 in two months is insane. Hell Ive landed over 100 perkies in two sorties one Saturday morning.
The individual player can make much more at a time depending on skill level and luck. I once landed myself almost 100 perks with one sortie, no rearm, and I could do about 1000 per tour when flying fighters more than I currently do.
But that's far outside the scope of the average AH player, which only gets about 3 kills per hour in the long run. In the past I estimated perk gains based on those stats, i.e. k/h, k/d and which planes are generally beign used and killed. I can do that for all players in the arena.
And 3 kills means (at balanced sides) slightly more than 3 perks on average. (Boosting perk gain by flying ENY 30 planes isn't an option for many players)
And currently I'm using the new achievement sheet in game, which tells me exactly how many perks a player earned since the last reset (end of january), and his peak perk balance. It's still in progress, that's why I haven't published it yet.
So far I sampled about 100 players (randomly chosen amongst those that had been active for at least 3 tours), and the
really good ones have earned in the range of 500-600 perks, one topping at 984. But that's a very small minority of players
