And also take in mind that KNC have stated that "the spec of Jupiter will remain a guaranteed minimum 400 GH/s we can confirm that we are expecting to be over that mark by a considerable margin."
I just want to know what "considerable" means... 10%... 25%... what is considerable?
It's irrelevant as they don't have an working samples yet, it's just marketing spin until they actually measure it.
Not really. They likely have good reason to believe it to be true. It's all part of their UPOD (under-promise / over-deliver) communication strategy. Remember on day 1 they were talking 250gh. Then it was 350. Now 400. Now they're saying over that even by considerable margin. Probably closer to 500 was their original target all along.
