What is the actual amount saved? I'm assuming this is like a regular 1/2 limit game, where the blinds are .50 and 1.00... so he is paying essentially 0.5 BB per orbit instead of the usual 1.5. That would be exactly 1 BB saved per orbit, which at a full table is 10 hands.
Wow, pretty good scam he's got going. Poker Room really ought to fix that. I can't believe you can cash out to that low, or buy in with less than a full big blind... what a crock.
