Too much research for me to undertake, as I'm at work now as well. I do know I had a 1.17 KD in BLOPs, but didn't play much, and only 7,000 kills in MW2 and played no multiplayer in any COD before that.
MW3 I have about 82,000 kills with a 2.51KD. Nowhere near your win/loss though I win like 59% of my games, but I run solo 99.99% of the time. I estimate the times I run with a team my W/L is closer to 5:1 or higher
Has for kd i would have to estimate becasue my son plays on my account and always goes like 10-28 or so lol and since infection has been around he will go like 3-20. So I would estimate my kd to be around a .90 or so.
As for w/l I play solo so its only around like a 1.14 (MW2). For some reason on MW3 its only like a .80 or so and I think its because on MW2 even if my team was bad I could control the flag areas good enough to carry my team due to the spawns not being so random. Not to mention my son plays MW3 more than he did he did MW2 so the stats are not all mine.
An interesting stat I added up the other day is I earn most points capped around 30% of the games I play.
