There's a section about VO2max estimations in our help: https://help.runalyze.com/en/latest/cal ... o2max.html
The athlete's correction factor is an essential part of all the calculations. It is required to correct the individual behavior of the heart rate (some people run a 10k at 92%HRmax, others at 88%HRmax). In your case, your individual correction factor has been recalculated after importing your current race.
Please take a look at the tool 'Analyse your VO2max'. You'll find a list of all your races and their estimated VO2max values as well as their correction factors. The automatic decision which of these factors is used, is not easy and not always correct. You can set a manual correction factor in your configuration.
Looking at your data, your new correction factor does somehow match your latest race (as 36:09 equals an effective VO2max of 58.5). Still, your shape is far away from that. What kind of heart rate sensor do you use? Do you trust its data?
Besides, when editing an activity there's always to checkbox whether this activity should be included for your VO2max shape or not. I always recommend to exclude warm-up and cool-down as well as activities that deviate greatly from your form. Still, there are a lot of activities in your history with strange behavior, e.g.:
- 4:20/km @80%
- 4:17/km @74%
- 4:43/km @73%
- 4:41/km @68%
- 4:02/km @80%
- 3:40/km @78%
There's no good fit possible of how your heart rate relates to pace.
