Hello. At the beginning, I apologize for my english.
My test result from the new version (tested several days) , 4xGTX1060 6GB +150GPU +400MEM 70% POWER
v5.6 - average monthly payment 0.6-0.65 ZEC
v5.7 - average monthly payment 0.5-0.54 ZEC
v5.6 ~ 1200sol
v5.7 ~ 1220sol
Why is the payment lower?
I will have to return to v5.6

Difficulty has increased, the miner should be working fine. Difficulty has increased a lot since ZCash price has increased. Plus, last month was a godsend. When NiceHash went down, all coins difficulty dropped quite a bit. Slowly but surely, that difficulty has climbed back up.
However, you should be mining the same USD value if not a bit more than before and your previous mined coins are worth more now!!
