People mining MONA might want to make sure that the hashrate reported by the client matches what MPH is showing. You may not be earning as much as you think you are. MPH is registering about half my hashrate. I stopped mining MONA since other coins/algos are more profitable.
I run a large hashrate on monacoin, I never really look at what the pools hashrate shows, however when i calculate the coins expected versus my actual hashrate and difficulty for each block, it is always spot on.
Hope that helps
