... There is also a chance that the SP31 performs like SP30 should have at ~6.6TH but I'd guess it's more likely it ends up closer to 4.5TH ...
Our commitment and guarantee is for 5.5 TH/s +- 5% with 3KW at the wall. It will probably preform better with the production tweaking we're doing.
By guarantee I mean that we'll compensate for missing hash-rate by the $/GHs ratio of the deal.
