Hi there,

I have been finding differences above 15% between the online Profit calculators and the projections from real mining.

Here one example for ETH mined with a 124MHs rig:

Cryptocompare: 0.816 ETH per month (124MHs rig)
https://www.cryptocompare.com/mining/calculator/eth?HashingPower=124&HashingUnit=MH%2Fs&PowerConsumption=1000&CostPerkWh=0

and

Ethermine pool stats: 0.646 ETH per month (124MHs rig)
ethermine.org

Any comments?
Do you find same differences?
