Well, I'm done for now. I was mistakenly working with an old cost/kw, thinking the base was 7½¢ per but now the base is up over 8¢ and realistically working the gross cost per kw, 10.147¢. I was running two S3's, 1½ S3+'s, two C1's, fans and pumps, window fan, and 1 S5, plus 2 laptops (could have gotten away with one). Took two days meter readings, 112.5kw each day, then 24 hours no miners, 16kw. Now there's likely a sliding scale with a lower surcharge with greater usage but this tells me that discounting that my base usage will cost more, it cost me $348 gross per 30.5 day month, $49.52 per month non-mining related, or $298.48 in mining costs (not counting power supply repair parts costs) while I took in ~$247 last month. Or I lost $51. I'll go a few days and get a better average for non-mining costs, then fire up the S5 for a day and see what I get. But it looks like I'm done except in winter and that's relatively short down here in rural Georgia.
That's the harsh reality for low scale miners, hope you will at least ROI after you sell the miners.
