I have to suspect a fair amount of it is asics. Unless the rumors of thousands of GPUs at a time going straight from factory to mining farms in China is true.  There simply have not been enough GPUs distributed in the "western" world to equal that hashrate.

As for the Shuffle, I went from 4 of 7 - 6 of 17 - 6 of 36.  The odds of winning seem extremely worse now, even with 20+ combos dropping each day lately.
