in all your examples, the distances are much shorter (every thousand hands is of great value for such a win rate!). at the same time, people in lineups with fish won this money, playing one or two tables for a long time.
in my examples a "monster" enters on nl500, sits at all free tables (they can have up to 9 tables on average per session), for 10 sessions in lineups without a select wins 50 stacks and disappears! "800 dollars per hour is too little for me, goodbye!" (hahaha, of course) and a new account appears at the same time with the same winrate and similar stats! what a coincidence!
