went to showdown is high for fullring.. These also probably leads to your problems @ W$SD because you are taking crappy stuff to showdown; whether it's checked on river/you bluff/you call with mediocre crap.
uhm.. wat? How large is that sample these stats were drawn from.
you should win money at showdown at least 50 of the time. Either you aren't folding or your are bluffing and getting called.
