Strange, have you tried Nicehash?, in NH profit is not an estimation, is real price of power selling.
Running the Nicehash program shows that I am in the $14 day range.
It's also possible that I just don't understand how the Megaminer works. Right now on Megaminer, it shows Blake2s from Zpool as the top Algo at about $18 on Automatic24h mode. At the rate it's running though, I might get $7 in the 24hours.
