Showdown won%

[Psycho21]

I've never really thought showdown win %. I use the stats window to keep track of how many hands I play on PP, and after 500 hands of 5/10, 10/20, and 15/30 I usually have a showdown percentage in the neighborhood of 90%. Any thoughts on that figure. I kind of think it is too high. Anyone else keep track of this? Any feedback is appreciated.
