Specification for the cron Scheduler in the Translation Platform Configuration

[thebestusernameifound]

Is there a minimum/maximum value accepted for the Scheduler Cron expression used in the Translation Platform Configuration?

The default value works of course, and it still works fine if I set, for example an hourly frequency, but I start to get intermittent missing tick as soon as I set the frequency down to every 10 or 5 minutes. Sometimes, it works well up to a point and then the scheduler just starts not syncing and then hours later it is syncing again. Is this the expected when using such a low value for frequency?

I'm on AEM 6.5.23.
