This has to be looked up in the Arpad's Elo Elo-table.

I remember that, for a difference of 100 rating points, the winn-loss-percentage
for the stronger player is 68-32 (if my memory serves well :-).

a win-loss percentage of  70 pct (or scoring 7 out of  10) would correspond
to +/- 112 elo points (but i would have to look it up in my library at home to be
sure).

Cheers,

Hans
