Hi,
I have recorded rides with the Edge 830 which have shown an increase in cycling VO2 max, and the Edge's training status is displayed as productive. On the 955, and on the Connect section for the 955, the training status is displayed as unproductive for cycling. The increased number for VO2 max is displayed correctly on the 955 and on Connect, but an arrow points downwards even though the number has increased.
Another issue is the advice given is to reduce high intensity activities, even though the load focus section says I am deficient in high aerobic and clearly states that I should do more.
