well, when pings are from 100 - 150 then hit bos is about 0.3 meters away from the body..
pings from 150 - 200 are about 0.6 meters away..
200 - 250 is about 0.8 meters away...
250 - 300 is about 1 meter away..
300 - 350 is about 1.3 meter away from the body
350 - 600 pings are about 1.8 meters away.. Try the distance and im sure it'll work cuz ive already killed a lot who has the same pings as you conisdered above..
Lag issue is to do with FPS limit too, sometimes the graphic card cant take the quality of the game and what happens is that comp becomes warm and you start to lag in game, if you c-bug, they wont notice you doing is cuz in their pc all it is, is slowmotion. In that case, shoot slowly with no c-but so they take the hit! IN cases as they run but run slowly are examples to do with navidia.
About H3iiZ3R, hmm.. try 1 meter away and it'll work!
IVe already got him down with 1 meter hitbox, he is just 1 meter to the left or to the right but you see it wrong way so try 1 meter forward to the right or to the left..
GOOD LUCK killing him
