I’d like to have the decoupling %-age for the ride among the metrics somewhere up top of an individual activity page. I’m pretty sure it was there when I started using Intervals a while back but no more.
I’m most likely missing out on something very basic as usual, can someone set me straight?
No, those are unfortunately not my numbers 
Agreed. I am almost certain it used to be there too but maybe I’m wrong
I don’t remember it being there…but you can do this with a Custom Activity Field
I think the following code should work…
decoupling = activity.decoupling
That will take the calculated decoupling on the Activity Power Page and put it at the top of main page of every Activity
Nice one. Thanks! I have that done for max session power. Never thought to do it for decoupling
Fantastic! Great 
That turned out to be the proverbial piece of cake. I’ve been struggling with some real basics for setting up “my” Intervals and twice now in a short while I’ve passed two, IMO, important hurdles in understanding the interface and creating customized pages.
So I’ve now added my first script, an excellent and very easy intro down a long and winding path. Really nice, thank you very much.
Just a short follow-up, see the screen capture from setting the script. I’m not in that bad a shape. What is the 42/42% about? A default number for seeing what a certain color will look like when applied?
It is indeed an example of how it will show up with number format, units, pre/suffix and text colour.
The number itself is totally arbitrary.
