Andy, to make a grading system to be as sound as possible surely we need to compare like with like. The current system compares people who play a different amount of games as well as giving some people arbitrary bonus points.
A rolling grade would also use a sample size, but it would be the same for all players.
It could be set at the 30 last games played although I would prefer a lower figure of 15 or 20 to be in line with the amount of games played per season by more players as well as allowing outlying results to be discarded quicker.
Juniors will gain more points when playing adults than they do at the moment which should along with up to date grading counteract or surpass any loss of points that they may occur when playing fellow juniors.
I am not suprised you found little difference in grades in your simulation. Whether that makes me illogical I couldn't possibly comment on!
