Thanks, I got the numbers! Really hard to mine if you don't have energy really cheap.
Yeah cheap power and luck are big factors if you want to mine at 20kwatts an hour or more. 20 watts is around 6 s19's which means it is out of reach for almost every homeowner.
and it is only earning 6 x 100 x 9.4 cents = $56.40 per day. Before any and all costs.
