Slash, sample size is way too small - those figures are irrelevant.

??? - stop for a second. Your biggest leak isn't that you are winning <50% at showdown; this is simply a statistic that tells you that there are possible leaks at some point in your game. In itself it means nothing, other than to indicate you need to look for where you're going wrong.

Also, it is possible to be a winning player at <50% - I can't for the life of me get mine above 48% and I'm a lifetime 6PTBB/100 player.
