I would think being 25/20 would be good VPIP/PFR for $50NL 6max. This is assuming you are solid postflop. What's ridiculous is you go to showdwon 4% of the time but you only win 53% of pots. You need to go to showdown more and keep that number relatively the same. You are folding away too much value. Im 27% WTSD and 53 W$@SD.
