Garmin Accuracy Again
It seems that just about every one of Garmin’s metrics has a detractor these days.
Raphael Fais bemoans altitude acclimatization. What does he know about it? Well, what does he know about it other than a PhD in the subject?
As of today my VO2max shown in HRV4Training is 8 ml/kg/min lower than what Garmin says. They have the exact same data.
@MarcoAltini wrote the HRV4Training algorithms. Again, other than a PhD in VO2max what does he actually know about the subject?
FWIW: My VO2max data in Apple Health is 0.2 ml/kg/min lower than in HRV4T. IE they are the same if rounded to the nearest whole number.
%age Grade on a Slope with the Edge 1040
We’ve all stood on a slope and realised that it’s definitely not flat. I guess neither you nor I have a PhD in slopes but experience tells us that something isn’t flat.
When I last stopped on a freakingly steep (20%) bumpy, off-road track with the Edge 1040, it showed a zero gradient. Clearly the 9438 viewers of this topic on the Garmin Forums, share my real-world experience of slopes. Actually, they are more complaining about the lag of showing the slope data but I think the underlying problem might be that at least part of the slope algorithm comes from 3D GPS positioning. Hence when you stop it doesn’t work…and this is for the flagship 1040 right?
OK, I’ve only got a business degree so I’m definitely not qualified to comment on statistical correlations to HRV readings. But I am definitely qualified to read. Try this…
The resting HRV data is wrong for me, which I outline in this post about the Garmin Morning Report – a great feature, shame about the data.
Other User’s Data
Here are some HRV data from the 955 from Marco Altini. In his case, the results look more in line with the other than mine, although not that I think his 955 data set starts to produce results on 1 August. I’ve collected my Garmin hrv data for longer.
