The first version of this is now live. I added decoupling along the bottom. When you have some decent drift going on as in this ride it works well and lines up with what the power and HR traces are doing . The decoupling numbers come out a little different to the current charts as there is no attempt to remove coasting and so on like the others do.
If anyone has any long endurance rides done on an indoor trainer please msg me link. I don’t have any of those myself and outdoor stuff is always quite messy.
