what a player REALLY want to know is how many people are better (in percentage) and how many people are worse
Nope. I don't care for a percentile, a rating system is much better. If I go from 47th to 50th percentile, I have no idea if I got worse or if others got better. If I go from 1350 to 1273, I got worse.
please calculate players PERCENTILE after every game in the LIVE Chess (beta) program... in addition to the rating... somebodies percentile says more than somebodies rating... for example you are among the tenth percentile .. meaning only 9 percent of the players is better than you
rating in it self does not mean anything...
and percentile is very easy to calculate I am sure... in freechess.org they do it to and it is very satisfactory... what a player REALLY want to know is how many people are better (in percentage) and how many people are worse
