For anyone that regularly uses the scheduled charging feature in their MS, does it work reliably? I have time-of-use electricity and the rates vary significantly based on the the time period (from 17 to 44 cents per kWh). The Super Off Peak period is 12 AM to 5 AM, when I will be charging my MS on a NEMA 14-50 50 amp circuit. If I plug in the MS and have it scheduled to begin charging at 12:00 AM, does it reliably begin at that time (e.g. Not before that time or after that time)?
