Is SRBminer showing higher hash rate than reality? I understand that the hash rate reported on pool's webpage is only an estimate. But still, I only have 24 hr hash rate fluctuating between 6.5k ~ 6.9k for the past week, all while SRBminer reporting a steady ~1850 hash/s for each 4 of my vega 56 throughout the same period. 
I have in total 70500 hash/s but in the pools show 58-70, lot less too
you should try it on a other pool, or try other miner on supportxmr for the same period.
Tried srbminer 1.4.2 with imagreedybastard Mode activated (no fee) and works fine. Im confused
