Yeah, typically a batch that I have seen is about 30 hours. Take note, not to overload the machine. It can only handle so much water before the need of defrosting. I am trying to minimize my efforts in the process, rather than trim off an hour or two here and there.
SatelliteDr,
I love the graphs. I was going to try to do this in Excel, but after messing with it, I figured I may try to run it through one of my linux servers tools, like rrdtool. Would you mind posting what you have done? We all love pictures.
