The synthetic job scheduler executes jobs according to the following cron-based expression:

When you schedule a job, you choose how frequently the job runs. It is recommended you choose a larger unit of time (hours or days) that can evenly divide into the smaller unit of time (minutes or hours). For example, if a job is scheduled to run every 15 minutes, the job runs four times within the hour. This results in the job consistently repeating every hour without interruption to the schedule.

However, if you schedule a job such that a larger unit of time that does not divide evenly into the smaller unit of time, such as running every 50 minutes, then the job does not run at consistent times. For example, if the first job starts at 7:03, then the job will run at 7:53, 8:03, 8:53, and so on, resulting in a disruption to the schedule.
