Re: WHAT IS DERBS SCREENAME ON PP???
"Your assertions would also seem to imply that DERB can not run a confidence interval on his own stats."
He can, but he would be using incomplete information to come to his conclusion. That's the problem. If he had no other knowledge of the situation other than his own win rate and SD, this would be his best bet. We are working with additional information. If you win 6-9 BB/hr with 99% confidence according to a Z-table, and no one else in the world wins more than 3 BB/hr, there is clearly greater than a 1% chance you win less than 6.
"but does this really mean that a sample of 100K hands are rendered meaningless just because we went looking for a LAG that is a winning player?"
They are not rendered meaningless. They are mitigated to a significant (but arguable in magnitude) extent.
