K-factor

The Elo system, born in chess and now everywhere from tennis to video games, turns a rating gap into a win probability. Every 400 points means a tenfold odds advantage. After each game, ratings shift by the K-factor times the surprise — beating a much stronger opponent gains far more than beating a weaker one, and an upset costs the favorite dearly.

A win probability64.0%

B win probability36.0%

A rating if win+12

A rating if loss-20

Governing equation

E_{A} = \frac{1}{1 + 1 0 ^{(1500 - 1600) /400}} = 0.640, R_{A}^{'} = R_{A} + 32 (S - E_{A})

Reading this result: A is rated +100 vs B, a 64% win chance — every 400-point gap multiplies the odds tenfold. With K=32, a win nudges A by 12 but a loss costs -20, so beating a stronger foe pays far more than beating a weaker one.
