Mining calculator give very different results

I am testing vs

Mining etherum coinwaz was profit of $8.06 per day from one rig. Zec it shows $5.95. For the same rig. This is after power costs.

Cryptocompare show eth $6.82 per day and zec $6.18

I don’t know coinwaz shows eth as so much higher then zec. I know coinwarz shows the current coin difficulty in the calculation. I wonder if cryptocompare is not adjusting the difficulty?
