Thanks for the reply. I already stopped the benchmarking and switched the card over to mining Verge for a day or two while I sort out what went wrong. Based on the copy-n-paste of the miner window output above it looks like the connection wasn't set up properly (ie - the stratum and port). Unfortunately, I didn't check the miner window at any other time so can't say if this is anomalous or not...
Don't even worry about troubleshooting timetravel. If the algo isn't included in your .bat file nemos won't benchmark it.
As nemos benchmarks each algo (which takes up to 6 minutes per algo *never* hours) it creates a file in the Stats folder e.g. ccminerpolytimos_ALGO_HashRate.txt If a file exists it won't benchmark that algo. So if you want to rerun a particular benchmark you can delete the relevant file and it won't have to run them all.
