If the chip is performing at that rate your MPP complaints are moot. You are already getting more than you ever dreamed of
Even if it is 800 GH/s (which nothing is confirmed that it is) it isn't more than we were dreaming about. Due to dificulty increases 400 GH/s on Oct 20 is the equivelent of not 800 GH/s but 1,532 GH/s on Jan 1. That's right if HF delivered 1,532 GH/s per BabyJet on Jan 1 miners would be no better off than getting what they promised (400 GH/s) when they promised (20 OCT).
So still think complaints about MPP are moot? Even 800 GH/s will be a 80%+ loss IF delivered on 1 January AND difficulty only rises 25% per adjustment. Of course all this is academic but it likely is NOT going to be 800 GH/s delivered and it seems very likely it will be even later too.
