Apple Watch Device Sampling Rate

Training
1

When I do a workout with an Apple Watch and sync the data to Intervals either via RunGap or HealthFit, I see this warning:

(example - Functional Strength Training)
This activity has been recorded with approximately 2 seconds per data point. Intervals.icu works best with a data point every second. Please disable smart recording on your device if possible.

Where is this set on the Apple Watch? In this case, I’m just doing functional Strength Training so basically it’s just reading the heart rate.

(Edit: Doing some searching, it appears that the Apple Watch behind the scene will vary the sampling rate, even for workouts?)

This has an impact when you record laps on the device. If the sampling rate is not 1 second then it isn’t possible to recreate the laps in Intervals.icu from the original data. So for if Apple Watch messes with that for workouts that will be unfortunate.

Is there a known method to disable smart recording on the Apple Watches?
