FR 955 Series: Training effect calculation is wrong AFTER 12.23 software (may include 12.27 and 13.15 sw)

Mine is 196, I am 34

220 - age = 186

My speculation is Garmin is using 186 as your Max HR.

Thus your activities load become more "heavier" than expected.

It would be good if users can share more information.

You are super stuck on this info. Running zones have worked for a long time with Garmin till the last update. Lots of Garmin watches have been affected. I had the 945 which was in the same boat. The issue is it's always using Max Heart rate for zones. Even if you set LTHR or HRR. My heart rate is 185 according to the Garmin HRM Pro auto updating my max heart rate and actually doing the cardiac test last year. I use LTHR because after years of running I know my perceived effort. If you look at the default zones and try to run easy you might as well speed walk. This is below junk miles even.

For someone who claims to still be on 11.12, DPSK is incredibly invested in troubleshooting this specific issue. 

I bought the watch like you do. I didn't get it for free.

But it is fine if you don't value my posts.

Now I get what you mean from the latest post.

You are wrong buddy.

I suggest you read the white paper again.

The zones are irrelevant in the TE. Your max HR is what matters. Somewhere in the middle of this thread, someone also pointed it out.

When you said TE was correct in the past, that's because Garmin was using the correct max HR.

Now the TE is wrong because Garmin probably got the max HR parameter wrongly.

The training zones are BASED on heart rate, whether you have them set by Max, HRR, or LTHR. If the heart rate calculations are wrong, then the time in training zones will also be wrong, so the point you're trying to make is irrelevant. We're all observing this issue because the time we spend in our zones is in direct conflict with the training effect calculated after activities. That's the most obvious way to see the problem. Unless you work for garmin and can actually fix the bug, knowing its source is meaningless. 

The point is, your speculation is irrelevant. Garmin is addressing the issue, we just have to wait. The most we can do as individuals let Garmin know we're experiencing the bug/problem. None of this applies to you if you're still on 11.12, which is why your level of involvement is unusual. 

Your statement is really like wtf.

1) I am interested to get the problem fixed because I want to upgrade the FW.

2) And this is a discussion board. So only only those having issues can reply?

3) And for christ sake, please open up the whitepaper. Point to me where it says anything to do with running zones?????
