Why does the Vo2 on my 955 not increase noticeably even though my training and variability are increasing. It was noticeable on my 935
In older models, the VO2 Max algorithm was accepting changes of 1 point (if not more) from one workout to another.
In newer models, the VO2 Max is changing much more slowly. It might be just a rolling average, we don't know. The best place to see the detailed changes in on the watch, under training status > VO2 Max. There the graph can show changes of less than 1 point. In Connect, the value is rounded to the closest integer. To illustrate, let's say 60.51 to 61.50, your VO2 max will be 61
