Dear Garmin,
I have been an enthusiast garmin user for the past 2,5 year, and last September I switched to the Fenix 7 Pro Saphire. My training has been depending lot on the data that the watch collected day and night, as I am wearing it 24/7.
However, in mid-December there was a software update and since the data is not useable. Without any illness (tested) and effects of overtraining my HRV graph dropped significantly and stayed in the red zone for weeks (as shown on the photo attached). With my friend who has the same model we have tested the reliability of the heart rate and hrv data. Unfortunately the findings are disappointing:
- First a health snapshot was made with and without HRM Pro band. It showed 39 ms higher hrv with the Garmin HRM Pro than without, which also influenced the rate of stress, even though the hr has stayed the same for both measurements. The results are attached with annotation.
- The second test was during sport. I want cycling and measured my hr with my Fenix 7 Pro without connected to the HRM Pro and with a bike computer connected to it. These results are also disappointing. The measurements with the HRM Pro were more responsive to the changes, and showed a lower average heart rate by 10 units over 2 hours. The evidence is also attached.
Before the software updates, after a rest day I usually had an avg sleeping hrv of 105-115. Since then, a good sleep only reaches 94 ms. The optimal hrv range has since adjusted itself, but still not works as earlier. Furthermore, the training suggestion is rest day since December, even though I have barely did any activity in the last two weeks of February as I was studying in a Library, when for one week the 7d avg hrv even reached the top of the optimal zone, and the training readiness was around 95 for days, and the training suggestion has been REST DAY! It is really disappointing that I can not use my watch for what I bought it for.
Can you please provide a solution after 2,5 months? Unfortunately my trust and loyalty for the brand decreases with everyday.
