HRM-PRO Running Dynamics + Vivoactive 4

Some data that the Vivoactive 4 does not support (like training effort and restitution time) is still stored in the fit-files, and can be found with third party applications. Has anyone checked if the running dynamics from the HRM-PRO could be there as well?

I can test it with an HRM-TRI that I can use. What app do you use to get the hidden data?

I don't, but I read here in this forum that Tredict and Runalyze can show the data.

I'd appreciate if you can test it out, as it would be cool if Garmin is actually storing that data, but I seriously doubt that it does.
I guess the best bet to get running dynamics with Vivoactive 4 is investing into Stryd...

But the Stryd does not have much running dynamics. I want ground contact time, mostly, but vertical oscillation is also interesting. 

I think that it does have that, at least it seems to based on this article: https://support.stryd.com/hc/en-us/articles/360055425073-What-is-Ground-Contact-Time-GCT-#:~:text=Ground%20Contact%20Time%20has%20an%20inverse%20relationship%20with,%28i.e.%20striving%20to%20attain%20a%20GCT%20of%20165ms%29.
but of course you would have top use their app to see those data.
