Thanks a lot for your article! I really learnt a lot. I have one question: When I take the LN of 250, this is 5.5 and not 10. Where are my thoughts going in the wrong direction here? Thanks a lot for your answer!

thank you Richard, multiplied by two plus a small adjustment to make it more human friendly (without altering relative changes within individual over time). rMSSD is also available in HRV4Training if you prefer

Thank you very much for your response, Marco. I also looked at the rMSSD and HRV values in your HRV4Training app, and I was wondering about a similar question. When my HRV was at 10, I was wondering about the corresponding rMSSD of 200 instead of the 250, you wrote in this article. Is there any individual or user-specific adjustment for these values, aside from the general transformation of 2*ln(rMSSD)?

correct, in the earlier days we also added an age correction factor, that aimed at making this HRV score more comparable between people. At this point I wouldn't do it this way (as the last thing we should do is compare HRV with others), but it's still there as it doesn't really matter for the typical within individual analysis.
