From an old PT database (back when I did use it) at 3/6. I folded on the river 42% of the time, 64% of the time I went to showdown I won.
The sample size was 9500 hands and my win rate was 6.14 BB/100.
Note: This is why I always say the long run is a lot longer than you think. Obviously I was running very well. I don't believe this win rate is ever sustainable over the long run. I know it wasn't for me.
