In another thread some are discussing what fraction of players
--might have once, or
--are capable of, or
--regularly
run 100 balls in straight pool
and the discussion brings home the difficulty of deciding who is a "player." Is it someone who has picked up a pool cue once in the last 6 months? Someone with an established Fargo Rating? The answer will depend tremendously on this choice.
Here are a few stats from the FargoRate database that illustrate the problem. The bolded part refers to players with an established rating, though outside the somewhat arbitrary choice of 200 as "established, " it is clear there is nothing special here. Better players play more and are more likely to have games that made it into our database. As more players come in, these distributions will shift.
The number of people with 50 or more games is 72,338.
