I picked the last one but I'm never gone or asleep for that long. Sometimes if it's hot out I'll run a fuse or higher temp glass load to be hottest in the middle of the night. I wouldn't set it and then go to BFE for the weekend.
BUT..if it's stormy with a chance of power outages (caused usually by the village idiots hitting the power pole down the street) I stay up or plan ahead. My annealer will ramp back up AFAP if the power shuts down and then comes back on. Not good for beads almost done. Ask me how I know.
