What is the average monthly kill count for the average fps gamer ?

I was wondering, if anyone of you gamers out there has ever reflected, how many video game characters he/she kills on an average (monthly or weekly). What would be the average number for all dead FPS characters, if you reflect your whole gaming career. I was just asking me the Question while playing GTA 4.|||For me, probably around 7,500 in FPS, like 30,000 in total
