I just completed a 34-minute commute using my 1040 (software 27.14) + HRM-DUAL (software 2.50) + Rally 200 (software 4.10).
Avg Power 165W / 1.71 W/kg
Avg Heart Rate: 121 bpm
(I can provide files to garmin engineers if needed.)
I earned:
Moderate: 1 min
Vigorous: 3 min (x2)
for a total of 7 min.
I would normally earn about 45 intensity minutes for the same ride.
QUESTIONS:
1. Is this a known issue, and is there a workaround?
2. Can this be fixed after the fact - for example is there a 'recalculate' option on the connect.garmin.com website when statistics are obviously wrong?
3. Can I manually calculate the intensity minutes (or estimate) and overwrite them somehow?
Sincerely,
---Tom
P.S.: The only thing that changed today is that I bought a second-hand Garmin Index 2 scale this morning and set it up right before my ride. I don't know how that could have broken anything, but it is always better to give more info when diagnosing bugs.
