Zpool profit estimates are way off! It seems only for sha256 coins!
It's off for sha256 too because it's a rolling average not a daily payout.. you get paid out every 18 hours so 12 hours is counted twice.
It is just an estimate, and as aaron6 says:
this is all that matters.

knowing that i am supposed to be getting only 0.007349 mining bitcoin directly i am doing good..
in reality the estimates are meaningless and nobody can predict how much bitcoin one coin can sell for before it happens.
just checkout the 24 hour payout and go from there.
