Garmin Active Calorie Adjustments

I had already checked that article before posting. The HR is fine, it’s a brand new Epix gen 2, but I do question the zones. Still I don’t understand that 400 calories this morning. It’s now 6 hours later and active calories is only 200 more, even after rowing.

See my previous answer. Time spent in individual HR Zones is being transferred by the device, so if the data does not come from your watch, the settings you did on the watch (even through the app) have no impact on itat all. You have to set up the zones on your rowing machine, or on whatever external device or app you use.

Could be EPOC. Check your Acute Training Load. And post a screenshot of your daily HR for the concerned day

I don't want to us MFP. I only used it because it was integrated with Garmin. I've been using MyNetDiary and have actually had enough of MFP after one day of using it today. Currently all I care about is making sure active calories and resting calories are in the ballpark of accurate so that I can send total calories to MyNetDiary. Even with MyNetDiary I question the calculations that MyNetDiary is doing with Garmin's totals calories because it's using verbiage like "MyNetDiary's Maintenance calories", when I clearly have a deficit configured in MyNetDiary. Another hot mess, but less than the MFP one.

The 400 is because the adjustment is based on an estimate projected forward for the entire day based on activity so far that day.  NOT the amount burned so far that day.   See here for details:  https://support.myfitnesspal.com/hc/en-us/articles/360032623871-What-is-the-Calorie-Adjustment-in-my-Exercise-Diary-    The calorie weirdness you see here is due to the way that MFP does their calculation.  (and it's just weird, I don't think it's wrong).  In theory if you just lay down and don't move for the rest of the day, I'd expect that number to actually go down from the 600 it is now.

The explanation of how MyNetDiary works with Garmin data can be found on this page with examples of how it does the calculation.

It seems pretty straightforward.   With regard to Garmin being accurate, if you wear it all day, and have your information (weight, etc.) setup correctly in Garmin Connect, it should be 'close enough'.  I haven't seen significant complaints there.

There are no zones in Zwift (the workout app used when this happened) that I'm aware of. I've only had the watch today, there is not data for Load yet.

The information is correct, but I do see in my workouts that Z5 is >156, but that should be 171 based on my configured Max HR of 190.

You should be able to check the specific values in your settings. (easy to get to in Garmin Connect).  If it didn't recalculate once you put a value in I believe you can manually trigger that.   You may also have set up sport specific HR zones, so you might want to check that as well.   Just guessing that this point 

I don't think it's sport specific because this are imported from ErgData and Zwift.
