Restart problem no kills but hight point

[lnxtv]

Iplay good for 3/4 days and i'v riched k/d 1.3 but like magic when I get to this point the usual problems start again, shots not registered, enemy not knoked, dead very fast etc etc....I also do 500 damage to 1 enemy and this not knok.

then I always suspect that something changes in the algorithm or rather you CANNOT exceed a certain threshold because it is really strange that you play well up to that point and then you no longer know how to play.
