For some reason, my 955 is ignoring the manually entered heart rate zones that I create to match my physiology. This manifests in all runs being catgorised incorrectly. For example, a Zone 2 Base run that is very definietly a low aerobic effort becomes categorised as a Tempo run. This also happens with Tempo runs being categorised as VO2 Max.
I had thought the issue was with runs that are 99% Z2 with 1% Z3 causing the entire run to be incorrectly categorised, but this isnt the case. A 100% Z2 run with a max HR inside Z2 often gets categorised as Tempo.
The knock on effect is that the entire training readiness and VO2 Max predictor seems to be wrong. Nearly all my efforts are classified as high aerobic, therefore the training status says 'low aerobic shortage'. I am apparently 'Maintaining' fitness with a stable VO2 Max, when in reality, my tune up runs have showed significant gains which allude to the race predictor being a lagging indicator, telling me what I might have achieved a month in the past.
The training load, training status and VO2 Max based race predictor are so inaccurate that I have to ignore them. This is a real shame as these could be awesome tools, if they worked accurately.
