Hadn't considered that. Doesn't it take like 24 hours or so for the net hash/difficulty to catch up w/ the actual hash rate?

Is all this hash rate new?

Edit:

I love the charts on the website.

Seems like the good doctor has picked up the interest of a large friend, looking at the chart, you're correct, we're dealing with both variance and a surge in hashrate within the last day:

Hope they're looking to hold!
