I have yet to calculate the profitability. This was an exercise in staying nimble in the market. Being able to switch miners and get from one coin to the next when the prices are moving is what I think is being good at this job... I think. I like the exercise, it keeps my linux and windows skills sharp. Ill post more here as I am testing new coins, and install methods and such. But for your maths pleasure, 19 MHs mined 0.12969689 CHC in 3.5 hours.
