A similar concern is why I set mine to start at about 45 minutes after the off-peak start time, when I was using the timed-start option (I'm using the timed-finish option now instead, so it starts at whatever time is necessary to have it charged by the time off-peak rates end in the morning - this seems to have a fair bit of built-in slop so if everyone used it, there wouldn't be the opposite problem of all the load disappearing right on the stroke of 6am).
