My Vo2 max has remained steady for 12 months. It used to switch up or down by one or two depending on activities. It dropped by a couple randomly last year and never moved again. I know vo2 can plateau if you are consistent but surely with some recent personal bests it should improve slightly.
My Lactate Threshold was last detected in January 2023. I wear an HR chest strap for almost every run. I incorporate easy/interval/long workouts 6 days a week. I exceeded my marathon predicted time on the watch a few weeks ago. LT would periodically update by itself (it's on auto on the watch) but not a thing for almost 18 months now. The data fields are just blank.
Surely there should be some variation in these over this period of time or at least some data in the LT to show it is being picked up even if no change at all?
