Sample size is stated in the original post and is for 7,685 players and 42,284 hands. It surprised me too. By comparison, players I have more than 100 hands on have a Fold to PF 3B %age of 54% (15,110 hands). Players with less than 20 hands are at 29.9% (29,194 hands). I wouldn't be surprised if the stats were dramatically different for FR on Stars.
