I did some further calculations....
Chris states that ONE 2nd gen shares yields the equivalent of 3000 Khs on Scrypt algorithm. Then, looking at its graph, one such share seems to generate roughly 0.0005 BTC/day if mining LTC. This makes sense to me, based on 3000 Khs, right? If my reasoning is correct, his graph indeed shows the performance of ONE 2nd gen share....then ROI is astonishing!
It does seem incredible if true but you also have to factor in that if he has sold 2000+ 10 share packs already... Then by January there will be a massive spike in difficulty when they are turned on. I hope not but realistically that many packs hashing the coins, even when spread out, will be significant.
