Just an observation (I haven't been tracking to gather empirical data) it seems like our big hash contributor is here to stay.  He's been onboard non-stop for awhile now.  Just wondering if there is communication with him and we know he's here for good now?  Or could there still be a rental in the future and we're back down to hashing at TH/s rates without notice?

Here's my rather selfish reason for asking-- Right now I'm splitting hash between pools.  If he's committed to sticking around and providing hash, I'd strongly consider pointing 100% of my hash here 100% of the time.  I'm ok with three four weeks between blocks (on average) if we can maintain 6P+
