The basic formula is 3 times your old rating plus some factor of your expected performance plus top 50 players get 1-50 points. I need help on how to work this rating as currently the top 10 players need to pass 70% in a week of hands to maintain their rating. Consistent 70% scoring in bridge is too much to maintain I think. Maybe if I change the top 50 players getting 1-50 points to top 10% of the weekly players which is currently just past 700 so 1-70 points awarded for weekly placing. I am looking to parallel to the chess ELO ratings.
Also I let the Bridge Now site method of drop 5 bad boards for over 70 hands played
factor in as the experience gained from playing lots of hands
From May 2017 I will decay inactive players by 10 points per week and use top 10% as the bonus
instead of top 50. Maybe the number of times your current rating should be higher like 5 or 7 or 10
as we are calculating every week a fresh rating.
