Big problem: Apple watch series 6 EXERCISE ring data not accurate compared to workout data! It doesn't match

Get the most accurate measurements using your Apple Watch

Calibrating your Apple Watch for improved Workout and Activity accuracy

You can estimate your maximum heart rate based on your age. To estimate your maximum heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum heart rate would be calculated as 220 – 50 years = 170 beats per minute (bpm).

Thank You ‘fieryjack’ for posting your exercise mins information which originated from an Apple Support phone call.

I to am trying to understand just how the exercise mins are counted, and get exactly what you state which makes logical sense to me and I can understand.

However I walk many miles per day and recently, since several weeks, I have noticed a “notable change’” in that the exercise mins the app credits me with have become a lot more mean. Perhaps this change correlates to a past watch update or code change in Apple’s software?

Do you think that arm swinging matters and is something apple have factored in, I am sure I read that somewhere but can’t find it now.

Here’s some data from walks I did yesterday and today

Yesterday

24 July 2021 0634 to 0929 UTC

2hr 45 mins actual walk 165 mins

76 BPM

18’ 36” mins per mile average

785 cals

I was credited 129 mins exercise for this walk a whopping 36 mins short

Today

25 July 2021 0559 to 0845 UTC

2hr 44 min actual walk 164 mins

77 BPM

18’ 08” mins per mile average

798 cals

I was credited 156 mins exercise for this walk only 8 short

I made a point of always swinging my left walk arm today but yesterday was not doing that as was reading and using iPhone as I was walking.

That’s the only thing I see different for this scenario.

What’s your learned understanding of this scenario?

I guess my Apple Watch fitness just became useless to me. You can’t go by a standardized chart when you have bradycardia and your heart rate is low to begin with. If I get to 80 bpm, that’s a high heart rate for me considering my resting rate is in the 40s and 50s.

Thanks. I had considered all you suggestions and have it set done and considered.

I have come to the conclusion I need to make sure I do always swing my arm and not use it to look at my phone as I walk.

If I swing my are I get the full 15m exercise every 15m (or sometimes 14 or 13)
