We have 86 machines currently, S9's and some 741's. We had to take hash on and off the farm over the past few days to balance temps during this insane October heat wave here in Virginia. I can't ever remember ambient being 94/76 in October before. Should be like 68/45 this time of year. One thing I can't control is the weather. So for the last week we had periods where we were stripping down from 1PH to around 600ish TH and Monday we had to strip it down to below 400TH for a few hours. We're back at full capacity today. It was nice that our 5ND average eased down and never dropped below 650ish, so our block rewards during this period were subsidized by our previous average. This was especially nice on the 9th when the pool got 4 blocks. The ramp up period of 3-4 days can be a bit painful,  but once you are fully 5ND vested, you'll appreciate it as an extra benefit of mining here.
