I'm at nearly 6BTC mined over the last several months at middlecoin.

Just FYI:  my average over the last 14 days at MC (actual paid to my wallet, not unexchanged/immature): 0.016295714 BTC/MH

For comparison:

14 Day Wafflepool average: 0.01116903 BTC/MH

Can't find long-term stats on any other pools to compare to, but I expect the law of averages still favors MC.
