imagine someone with 1800 points playing against someone with 19 points and loosing. so he looses 1800/19*20 which is 94.73684211*20 and that equals 1894 points. So let me ask you this: would the person with 1800 points who lost 1894 points now have negative 4 points?
The most you can loose is 100 points per game and no u cant get negativ points 4 divided bgy winners score wud only go to a half and maybe no points wud be taken from the loser
