Since I've installed the 18.20 my VFC is always on the lowest part of the graph. Has anyone the same problem, I've started to worry about that. I've been waiting a few days if I'll get ill or another problem but fortunatelly nothing happened.
Thanks
Yes I'm on 18.23 and have seen the lowest values for HRV ever recorded for me in the last week or so. My range is generally between 60 and 80 for the last 18 month or so and this week it was as low as 20 and max 40. Was also worried as I've found this value correlated well in the past for me with illness.
