@bravenel - I saw something you wrote recently relating periodic schedules, but cannot recall or locate the related post. Are they working correctly? My ISP modem is getting long in the tooth, but since I own it, I'm going to try a reboot in the early morning every two days, as that seems to correct its issue.
We removed every n seconds and every n minutes from Periodic. What you have should work. You can look at the app details page to see the scheduled job for it.
You could do it with Repeat every 10 minutes. Question becomes how you start this happening, and how you might stop it later. You could also use Periodic, which solves the first part. Set it up in a trigger, and select every 10 minutes.
