Hmm, I have the Android app and it gives a rating estimate on the settings screen.
1 is 400, 2 is 600. It increases 200 all the way to 9 at 2000 and level 10 is listed as 2600.
Now, that said, I'm betting those values, especially at the lower end, have a pretty decent margin of error.
i was wondering about the cpu strength on my iphone. the setting is 1-10. what elo strength is 1, 2 etc?
