Interesting, I’ll have a look at what the data says.
Re. Sleep tracking, do any devices substantially improve upon time in bed? Again my watch really struggles to differentiate between sleep and anxiety ridden ceiling staring.
ewanmac-
Not really. Most consumer trackers are pretty poor. I remember listening to a sleep scientist podcast and they had found a 'sort of' consumer level tracker that was almost as good as their lab kit but it was still something like £1000 or $1000.
Here's some actual testing of consumer units:

hippy
If I can be arsed I look at the HRV data dervied from a running activity recorded on my 935 whilst wearing a HR strap (since the optical monitor can't get it).
I think you had to enable something to tell the 935 to record HRV data. Yep:-
Garmin Connect and Strava do nothing for displayin HRV info but uploading those files to runalyze.com will give you some info.
This is a more specific analysis than the generic "how knackered are you" info that the Garmin will give you if you do:-
Training Status and Scroll down to the "Recovery" page which tells you how long it'll be to recover.
But none of this gives you general "you're knackered" based on your current HRV as it's just relying on data from your previous activities, and most of that is based on estimation of whether your recent load is too much or not.
