Watch OS 10.1.1 heart rate not accurate (alien.top)

Title says it all. After the update to watch OS 10 my heart rate complications quit updating on my Ultra 2 and series 8. I was hoping 10.1.1 would fix that. Nope. Now while doing a workout on bike trainer the apple watch ultra 2 was sometimes 15 bpm faster than on a Polar H10 chest strap. Today the ultra was 10-12 bpm slower. The Polar H10 is considered by some to be the gold standard for HR monitors so I'm pretty sure it is accurate. So disappointed with Apple this time around with the OS10.1.1 and the IOS 17.1 updates. If I didn't have so many Apple products I think I would jump ship and go back to Samsung. I know Apple will get it all sorted out out eventually, but damn

I highly doubt the OS is responsible for how BPM is counted.

How did the Polar and AWU2 compare before the update? What about previous updates?

Keep in mind with these "fitness trackers" that they're all relative meaning the exact numbers will never match different devices and products. You have to stick with a single device and take relative measurements. The exact numbers are useless, it's the trends that you need to pay attention to.

Have to disagree. Apple watches are the most accurate wrist HR monitors out. They usually run within 2 beats of chest strap. During workouts apple watch takes a measurement every 5 seconds, where as the Polar is every second. Before update they were within 1-2 beats of each other. 15 beats difference is a big deal when closely monitoring HR. It throws your HRV off, resting HR off, zone training off, max HR off, pretty much everything
