Would it be possible to have TD display HR decoupling since it has all of the information necessary to calculate it already? I don’t know the inner workings of the app, but it seems like an easy enough calculation to run and output.
I currently have to upload my steady state Z2-type rides to Intervals.icu and add an interval in order to see it. It would be nice to be able to see it within TD and avoid these extra steps.
That is a great suggestion and very unique and easy to do. I like it!!! 
Not sure how soon we can get to it but I will do it.
I have paid close attention in the past to decoupling, and ready to start again soon… Need to research it, the only complicated part is that we should ignore like the first 10 minutes during the warmup. And compare the rest of the workout. The initial part makes it a bit misleading, especially in 1 hour rides/tests. One thing you notice is that breathing can affect this a lot, it would almost be cool to have something in real time Need to think about all this more, but I still like it a lot.
Even if it’s not practical to display it in real time, I think it would be cool to have it displayed in the dashboard where the rest of the activity stats are. 
I will have to think about this. I do like the idea.
