Moving time makes a lot of sense for those of us that ride on undulating terrain. On a lot of my downhills I have to limit pedaling unless I want to crash going 50 kph.
When riding a mountain bike on challenging terrain even when I’m not pedaling, if I’m moving, I’m definately not doing nothing.
Not everyone is a roadie riding flat terrain or a trainer.
Fortunately you have given us the flexibility to do what works for our individual situations.
