my 8x p106 rig is pushing 104mh/s under pheonix/ dagger and my 2nd with 5x p106 is pushing 63mh/s under nbminer / dagger, both rigs are using nicehash.
i also have 2 hp work station
Z420 8 core Xeon mining XMRrig - GTX 1070ti @ 26mh/s under pheonix / dagger
Z800 2x 6 core xeon mining XMRrig - GTX 1060 @ 19.8mh/s under claymore / dagger
total profit currently on the nicehash dashboard is 7.50 USD per day
So you have 104+63=167mh/s on ETH correct? This yeilds about $5/day before any expenses such as power.
For your XMRRig with 46mh/s you should get maybe another $2-3 or so, so basically the $7-8 USD is correct.
What config did you put in WTM, maybe you made a typo somewhere?
