Backup when idle for X minutes does not work as expected

The biggest issue I have with Time Machine is high resource usage after awakening from sleep. Typically, multilple processes contend for resources while my Mac performs various houskeeping duties if I’ve stepped away for a while. I had hoped that Backup Scheduler would delay Time Machine activity until I had taken a break. It does not do this. As soon as the desktop appears after typing in my password Backup Scheduler is already banging away on my Time Capsule backup drive. Time Machine activity shows hundreds of megabytes being backed up, which leads me to believe that the not only does the “backup when idle” function NOT work on wakeup, but it can’t be working AFTER I take a break either. Otherwise there wouldn’t be that much stale data that requires refreshing since I last used the system.

Backup Scheduler seems to work OK for blocking the default hourly Time Machine schedule, but there are other ways to edit this schedule without purchasing Backup Scheduler.
