Mining is having problems. hashrate 6x1070 on the claymore is 185MH / s, on the pool is 197MH / s. Hashrate 6x RX570 on claymore is 165, on the pool is 218MH / s. rx570> 1070. There is an error here.
Pools give you a *Calculated Hashrate* - this is the number of shares you actually submit in a given time interval. There is still some degree of luck on the shares you find, so your calculated hashrate can fluctuate.
