In which pool(s) does this miner mine?
How much of the generated BTC is being paid out?
This pool uses several pools for failover: slush's pool, deepbit, and a private pool.
Right now the fees is 19%, but with a 4% discount if there is a link to Bitcoin Plus so the total fee is 15%. This payout is pay-per-share, so there's less variance than with proportional.
