There’s a field called “Total_Training_Effect”, that I have added in the custom fields.
It’s not the same as the Aerobic Effect and Anaerobic Effect custom fields.
I have a FR 735XT, so it doesn’t have the aforementioned fields, but it does report on this field.
Hope this helps.
Look on your Garmin summary page, and find the fields you want in Intervals.
Then upload the field to FitFileViewer and see what the field is called.
