Comparing training effect between Software Version

The question is if it's just the usual thing I call the horoscope effect, when 1/3 of the users complain that it underestimates, 1/3 that overestimates, 1/3 feel it's pretty good, when in fact it could just be "random" numbers.

Or, you need to make sure that the input the Garmin algorithm uses (i.e max HR, etc) are correctly set

Have your Garmin VO2max and threshold have been the same since the beginning Of these measurements? Once they change the comparison is worthless 

Just wanted to clarify that Max HR and LT heart rate are manually set based on measurements. And zones are set based on lactate threshold. VO2max is currently from the watch and not tested.

I have checked the white paper on EPOC to calculate training load and to my understanding it is based on % of VO2max combined with time. I cannot see any change in setting or my physical status that would explain such a big change in training load going from v21 to v22.

Thanks Karchevsky K and his findings about the effect of STRYD in this thread

https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-965/406231/actual-stamina-in-basic-running-training-has-become-noticeably-lower-than-potential-stamina

I tested by switching off my STRYD pods and using wrist based power, and suddenly the training load is back to normal also for v22.

So I will raise the issue with STRYD.

When you here from Stryd, could you please post their response here in this forum article? Very interesting to hear what they say. 

did another hilly workout without Stryd and with the stock Garmin power. Stamina was fine, power zones were generally in line with the load (taking into account the terrain) and running pace. The pace itself was pretty even, but I mostly ran in open terrain and set the GPS mode to best. also turned on the 3D speed and distance options.

I'm not sure Garmin needs this)))

If you mean Garmin needs Stryd, I think you are correct.

But I do think Stryd needs Garmin, therefore I am a little bit surprised that Stryd does not, as a partner reach out to Garmin for a problem that obviously affect several customers and might make Stryd unusable on Garmin. Does not seem to make a lot of business sense to me.
