I am up 235 BBs after 15k hands of .5/1 (I had a disastrous 5k hands of 1/2). Is this enough of a profit to be confident that I am a winning player?

Also, what is the best way to make a stats post? Take a SS of PT or just copy down stats? I have a general idea of ranges for stats from the stats FAQ, but I'm wondering if some of the stats are significant at 20k hands.

Thanks for the reply jph.
