Chess ratings

Here's the formula I used to calculate new ratings based on your Solitaire Chess score.
Old Rating/30+10 was your expected score for every 5 points you exceeded your expected score, you gained a point. For every 5 points you fell short, you lost a point. Biggest gains - Josh +6, Anton +5, Keighvin +3. Biggest losers - Tom McD and Misha who didn't turn in a sheet with their name or score, so I subtracted 3. I also subtracted a total of 30 points from various people who were talking or looking around the room when they should have been looking at the board.
