We're looking at the possibility of displaying a player's standard deviation at some point along with their rating. In the mean time, the higher a player's rating on average, the smaller their standard deviation. A player will shoot 2/3 of their rounds with a rating within +/- one standard deviation of their rating. The range of standard deviations for player over 1000 is about 20-30. That means a 1000 rated player might have 2 out of 3 rounds with a rating between 975 and 1025. For 950 players, the SD is 25-35. For 900 players it's around 30-40 and below that it's 35-50+. But there are exceptions at every level with players who are wilder or more consistent than other players in that ratings range.
