In my recent session I started taking a closer look at the showdown stats and they did not seem to make sense to me.

For example there was one guy who had the following showdown stats:

WTSD 0 (13)
Won WSF 9 (13)
W$SD 100 (1)
W$SD (ex small) 100 (1)

So in 0% of the time he went to showdown in 13 hands but won his showdowns 100% of the time out of 1 hand. Makes no sense to me.
