S9 baro not showing VO max

[markytarky]

Guys, I just replaced my old S9 baro to new S9 baro a the VO max is not showing. I ran yesterday for 10k and nothing. Does it need more runs? Thanks a lot.

exact. More runs, possibly with heart rate belt. The HR data is in fact important that it is consistent.
with another 3-4 runs you will see that the data will appear.
Of course, also pay attention to having set age and heart zones correctly
