I just recently started mining a bit at your pool, and I do have one question..
I understand the double geometric scoring system, and I love the idea of it...
I am curious, though, why my prop-diff is quite often negative. I'm not starting and stopping the rig, so I'm hashing continuously. Shouldn't I be at 0 or higher? What would cause me to get paid less than my share (proportional) if I'm not 'hopping' or taking breaks in mining?
Enigma
Well according to Meni who designed DGM there should be no loss of BTC if you do switch your miner on and off ... or hop.
Just no gain either.
Agreed, as long as I'm mining continuously (which I am), my understanding is that the worst case should be no difference from proportional. Gains can be had if OTHER people stop mining during a block, letting their share dwindle. That's why I don't understand the negative relationship to proportional in my case.
