Yes, the result is, but at the moment the gap is very small, but still progress is being made
That's why I will release a sp-mod ultimate with all kernals optimized. Decred donators wil get a 0.1 BTC discount. Profitabillity is changing from algo to algo.
I have optimized all the 17 algos from x1 to x17, When I merge my kernals into the latest 1.7.6 branch other unkown algos will be faster as well. M2m, c11, sib etc..
