Thanks for the info, very helpful. So in your opinion, I should use ethminer doing solo on my Geth? Even though CMD give me a higher hash rate? With either I get 103mh on 1 rig, with CMD I get 120mh. With all my hw, using Ethminer its 460mh, with CMD its 550Mh. Considerable difference.
Thanks,
Like all mining I think it is going to be luck that rules on this one. You could possibly have found an eth block in that 14.4 minutes a day that CMD is mining the dev fee. Mining Shift with only 50-60mh I have found that the 36 seconds doesn't really affect me. I get more from CMD on average than I do etherminer. If I had the hash-rate to mine Ethereum solo I might feel differently.
