What this work gives Aellic
The most-cited practitioner reference for HRV metrics and norms; its Table 6 carries the short-term norms from Nunan 2010. Usable only as a cold-start fallback — the spread among healthy adults is too wide to decide anything about an individual.
Correction of 25 July 2026
The registry attributed an RMSSD age table with “a 1–2 ms decline per year from age 30” to this paper. Neither appears in it — Table 7 names Umetani 1998 as the source without reprinting the values. See umetani1998 ; there the decline is not linear in any case.
The entry on the register was wrong. It was not replaced but kept — with what holds instead standing next to it.
Where this sits in the engine
This work is on the register, but nothing computes with it today — mostly because the feature it belongs to has not been built yet. It is listed so the numbers on the overview do not claim more than they carry.
