EDIT: Looking back at pass periods I don't think we are that close to the end game. I was confused how it works. If the difficulty leveled out, then yes we might move fast towards an end game, but that isn't likely to happen over 200 days. In that case the dividends just keep paying out until the funds are exhausted.
Don't kid yourself...3 PH doesn't just disappear from the network, and there's more coming from wherever that last 20PH just jumped out. More likely is a big operation took down part of their new farm for configuration before they jumped into round 2 here.
On second thought, I dunno...I figured we would have seen a recovery to the 125-140 PH/s range on the network by now. Its entirely possible that the last increase was fueled by added equipment plus a luck boom, but still, idk, something doesn't feel right here.
