I've had bminer 5.2 and then 5.3 running 24/7 for weeks and on miningpoolhub the reported hashrate and what's shown on the graph is much lower than what the bminer console reports. Anyone else get this?

A single GTX 1080 reports on average 620 sols/s, but the MPH graph will only show briefly hitting 0.64 once in a 24hr period, with the rest of the time hovering at around 0.5-0.55. I don't get this with ewbf.
