Wrist Based Running Dynamics

Hi everyone!

I'm absolutely newby in Garmin world - came here from 10 years journey with Suunto))

So, I configure running mode and in the Garmin Connect App and on the watch itself I see screen with wrist based running dynamics. But this screen is absente during the training and there no metrics in running statistics.

Also I'm pretty sure, that this metrics using for power calculation (It's mean, that watch calculate them).

And my question is: is it bug of beta firmware or marketing politics (e.g. "Instinct 2 not for performance athlets therefore we not show this data for this watch")?
