W$SD is around 50-60% for most players. It will be higher for tighter players and lower for looser ones. Don't forget that it actually shows the % of won pots but not how much money is won a player win W$SD above 50 is not necessarily a winning one.
A good W$SD is somewhere between 49% and 54%.\n\n In general, if your WSD is too low, then it means you are probably calling too many bad hands and/or bluffing too much earlier in the hand. If it's too high, it means that you are probably either not bluff-catching enough and/or not bluffing enough.
