That is odd.
What I noticed is that my Garmin watch may be wrong at times, but overall provides a fairly good and very useful assessment, especially comparatively day vs day and overall for trends.
In addition it takes a bunch of time for the watch to work out enough data to tune the algorithms for a particular person: some UI bits explicitly call out that for accurate results the watch should be worn continuously for ~2 weeks.
I've now been wearing this particular one (Fenix 7) for 6 months, a serious upgrade from a Forerunner 735xt continuously worn for 5 years. 95% of the time the watch is stupidly accurate in ways it has no business being as a simple wrist-worn set of sensors.
