Easy. Chess uses the Elo rating system.

I mean that ELO is not linear and there is no obvious ratio operation for ELO scores. How much is better than 2,600? Is it 5,200? Is it the rating at which you'd have 2:1 odds of winning a match? (Wikipedia says 200 points represent 74% chance of winning, so somewhere below 2,800) There's just no commonly agreed meaning of "50% better Chess player".
