I just changed the sql query and the output, had an example .js file.

Change the min_pot and see how your W$SD% changes, thats the interesting part. There should be a general increase from small pots to big pots for all players (because there are fewer players at showdown in big pots generally), but I think the big winners in the game will show a much bigger than normal increase because they are better at knowing when their hand is good (especially in big pots).
