Noob question about suprnova hash rate large fluctuations

Sorry for the beginner question...

My machines all stay at a pretty constant sol/s. They maybe fluctuate 3 - 5 sols indicated.

My suprnova dashboard has my hashrate fluctuating any where from 150 to 250 h/s.

What is the dashboard actually indicating and why the huge fluctuation?

thanks in advance for the education :slight_smile:

saw something similar the other day on own account and have seen others appear to be reporting similar inconsistencies over on main thread past 48hrs
