Would be nice for an “Injury Recovery Mode” though,let it be useful for 3-6 month, but as you coded it already. I am experiencing that now.
It’s possible you didn’t go above threshold for long enough. AFAIK, it needs to be for 1m before Intervals will calculate it.
I think he got that but he stopped the recording without letting the HR fall back. So there’s no recovery available in the data…

Here times higher values. They say yes you have to drive at least 1 minute or 10 minutes in Z5 so that the HRRc value is displayed. But why is it not displayed to me? Can someone help me???
It’s because you quit the activity before lowering your heartrate

You need to see a HR-drop in your data after the effort for the software to be able to measure the HR recovery. Like this:
Next time, continue recording another 2min or something after your effort!

Ok I use a Wahoo kickr v5 and an Apple TV 4K for Zwift. So after a workout I have to wait at least another 2 - 3 minutes until my pulse has dropped and only then save the data on Strava because Strava and Intervals synchronize together, that’s how I set it up. And then the HRRc value should be displayed at intervals? Thank you in advance and a Happy New Year 2022 !!!

It isn’t always at the end of a workout. It’s the biggest drop in HR after going over your threshold.
Example bellow shows on interval 3 of 5:

Coming back to this,
- I am wondering why HRRc is only evaluated when one goes over THR? I.e., when I do SST intervals I never get over THR yet still see very significant HRRc’s of ~40 over 1 min at the end of the intervals – and I’d like to have them quantified;-)
- Maybe it would be a useful plot to see HRRc against the HR from which it actually dropped, as a function of HR_peak or a function of time (date) – anything known about this, any thoughts?
I just assumed that looking at HRRc for starting values less than threshold wouldn’t be very interesting. I could relax this a bit but it would still be useful to have some min starting value (maybe 10 beats under LTHR?) just to avoid a lot of noise.
This can be done and is now on the todo list.

Yes, the “noise problem” is obviously there…
One thing is the rule along the lines of “1 min @ x” mentioned above.
Maybe x could also be a user setting defaulting to the current assumption of THR – which would have least impact on “standard” users.
For me HR during SST is often (just) below 0.9 * THR, the latter derived from 20 min tests.
SN: Which reminds me of the point that for me TRIMP loads are often a lot smaller than power based loads and that I was wondering if this was normal or a sign of poorly set (too high) THR? What would be the appropriate topic in the forum for such a discussion?
I think I will change it to be LTHR less 10 bpm. Thats simple enough and shouldn’t annoy anyone too much.
HRSS depends quite a bit on your resting HR being set correctly so it could be that?
Well, it’s too high a threshold for me. In fact, for me LTHR - 10 > 0.9 * LTHR > HR(SST).
The latter is which I would like to be incorporated in the HRRc analysis – how fast does it drop after a 10 /20/30 min SST intervals, etc. 
I assume that is the HR_rest set in the settings – which is set to a quiet reasonable value for me – these last weeks it is really about the average of my daily resting HRs.
This does not seem to be the issue here.
Nevertheless, would it be possible to have the resting-HR in the settings updated form my daily HR-data uploads using HealthFit?
Still wondering if maybe my LTHR is set too high, but it does come out like this from FTP tests/etc.
But also the TiZ looks very different for power and HR:
For Monday’s “tempo” ride the power distribution was
whereas the HR distribution looks like this
HealthFit should already update that field.

It does
(… although I am fairly certain that the field read 50 yesterday, but none of the recent readings is 50;-)
Also it did not really help my original question on HRSS (norm. TRIMP). Todays outside ride has these HRs and loads
Resting HR is from Apple Watch/Health, it is in line with (but not taken from) the HR of a 5 min mindfulness session in the morning…
Following up here, what‘s the status on being able to get a lower threshold HR for HRRc analysis?
Would be very useful:-)
One further example from yesterdays over/under intervals that shows a „funny“ HRRc because only on the very last I got to LTHR, so it determined HRRc there – but because I did not go all the way deon to „easy“ after the over, it did not „recover“ as much as on earlier intervals – yielding too low a value.
I added that in /settings for each sport with HR zones. The value is stored as a percentage of LTHR so if you change your LTHR it adjusts.

Please tell me if I understood the meaning of HHRc correctly?
Threshold heart rate - 176.
I run 5 intervals in the heart rate at the peak of 182.
After the last interval, I look to what value the heart rate drops from the level of 176 bpm in 60 seconds (146).
HRRc = 176-146 = 30 beats/min.
In the settings of the heart rate zones, I try to specify HRRc = 30, but I can’t, the following message appears - “LT HR must be between 80 and 220”.
