K/d ratio after a quit and rejoin

[HellfiG]

Hello,

I've noticed that my Kills- and death ratio (k/d-ratio) isn't what it should be.
If I play a map, and lets say after 10 mins I disconnect. Then after 9 minutes of afk, I rejoin that same map on the same server.
Strangely, My ppm are almost 100% correct, but my K/d-ratio is the k/d-ratio when I rejoined that specific server: WOOD
So my 10 mins K/d ratio just disappeared?

Can anyone confirm this?

I think I should have both demo's when I was playing, and when I rejoined. So if this would be necessary to check, I'm glad to look for those demo's.

EDIT: Well, I looked for those demo's in advanced. I don't have them. I only have the stats.
But it was on WOOD, so maybe the TB-guy from WOOD (Giriel) can get those stats? If it would be necessary to check if I'm not talking 'bs'.
