7 Days Rewards, 2miners vs Flypool

I made this test in the last 7 days.

GPUS: 8x RX6800

Driver: 21.4.1

Clocks/Undervolt: 1350 core, 2150 mem. fast timmings, 690mv

Hashrate: All between 34-35mh/s @ 118w

I setup 4 GPUS to mine on 2miners and 4 on flypool simultaneous, to match the same difficult.

Here are the results(rounded):
