Hi All, noob question here. I notices that some of my dives do not have the SAC rate calculated while others do. I'm using the same computer for all the dives so I don't know why it isn't being calculated. The dives range in time from 17-30 minutes. What are the requirements to trigger the SAC calculation?

This is under the iOS section, but the overall details apply to both:

Thanks Nick, I didn't think to check there as I'm using the desktop version.
Appreciate the help!
