The DWP should only be on until the first map change mate as the server had to be re-set following the update. If it's STILL on then please post here later and i'm sure someone will set it to off.
The points system is quite complex and i've gone over it before.
Basically it works as this : - You GAIN your vitcims points devided by your points x 5 x the weapon modifier.
Your victim loses the same amount of points!
So if you have 1500 points and your victim has 1000 and you kill him with a deagle you would gain 3 points and he'd lose 3 points
if he kills you though he'd gain 8 points and you'd lose 8!!
So as above --------> Kill good players withcrap guns and don't get killed by newbies
Also you get a fair few bonus points if you plant the bomb or defuse it or rescue a hostage
