Describe the bug "0/20 " cron pattern launches my tasks hourly while "/20 *" launches tasks every 20 minutes

There is a screenshot of my log stats from heroku for 0/20 pattern

there is one for /20 *

Expected behavior I expect these patterns to behave in the same way

Hey, man, "0/20 *" is not standard cron. Heroku ignores "/20".

Thanks for your response. I've already changed it to the standart pattern and it works as expected
