Originally posted by zzarkisOne of the Firefox RHP addons actually shows the percentages in the Player Tables for every player. All one has to do is find him/herself and you can see your percentage of games won/lost/drawn. I agree it would be nice to have this stat on the "My Performance" page.
A site improvement would be the addition of a 'percent wins' column on the 'My Performance' page - just need one column next to the total games 'Won, Drawn, Lost' columns to show our overall performance. Omit Draws and show the percent Wins of total Wins plus Losses.
