I mis-read Frank's post and thought he had personal knowledge that the btcguild hashrate was hashratio.
I was referring to the btcguild hash rate being attributed to AM.
It happens but yes, the user 67117 is (or should be) AM. That was their account on BTCGuild before they went solo, way back when.
The hashrate appearing on BTCGuild could be from the franchised miners. AM could assign a worker to each franchisee, so all the hashrate AM owns through franchising gets pointed to one place.
It could be AM themselves, rolling out equipment until they get to the point where switching to solo-mining makes sense again. I guess we'll just have to wait and see.
AM uses a calculation to determine how much BTC each franchisee owes them per difficulty adjustment period. There would be no reason to have them mine to a specific pool/worker address.
