Thinking about it some more, this only fixes the problem if the computer is actually on at midnight. If the computer is switched off overnight then we still try to start three maintenance jobs at the same time when the user turns their computer on on Tuesday morning. We could stop marking the hourly job as persistent on the assumption that it will be run soon anyway but that does not solve the problem of the daily and weekly jobs running concurrently on a Tuesday morning.

Best Wishes
