What's up with the profitability? I'm not getting 1/3 of the projected profitability.

Probably orphans / rejects because nitro owns this coin.
Damn! I might go back to clevermining until nitro launches the second pool. I'm currently mining at leetpools but only 0.05 btc a day is pretty low, considering my power usage - 15x R9 290. By the way, does 2330 mh/s sound right for this sort of setup?
Thanks!
