This relates to what I wrote earlier about differences between previous versions of the apps. From the start, Bioforce had the ability to flag significant relative increases in HRV as parasympathetic over training and would give an amber or red warning. In version 1 of ithlete this did not happen and the same data would have a green indicator as if everything was ok. Ithlete version 2 included this feature and so the information you quoted is no longer accurate (except the length of the measurement period).
What did you ask them? Let us know what they say.
