The highest I can find is 4600 points and it says they played mostly blitz, which is still a LOT of hours. And a high winning percentage.
Mathematically it's not possible since the leagues haven't been up for the amount of time it would take to gather the points. Or it's a bug which has some flaw and gives out too much points for something, or the person is cheating with another player and resigning to each other after move two for a lot of games.
If this is true, how do some players already have thousands upon thousands of points?
Playing a lot of games. I got around 60 the first day in around 40 minutes in an arena.
Some have more than 5000 points, which means 700 rapid wins, does that sound realistic to you?
