That that would make it 5200BB/20000 or 26BB/100 hands in earnings.
um...wouldn't that be 13BB/100 ?
according to Poker-Tracker:
BB = Big Bet = 2 x Big Blind = $1 at NL 0.25-0.5
so $2600 = 2600 BB which gives 2600BB/20000 = 13 BB/100 hands

this stuff still confuses me, but I think I got it right this time
