If you've read the paper on the website describing the ratings formula,
you should have noticed that performance rating isn't really a factor
anymore, it isn't even computed except for provisionally rated players.
The pre-event rating is a major component in computing the K factor,
and the effective number of games, and the difference in rating between
the player and each opponent determines the expected probability of
each game.
The bonus is essentially the same formula, but the maximum bonus available
drops as the number of games increases.
