When I switch to resistance mode I notice there is a little slider at the bottom left(ish) of the workout screen titled ‘resistance’. On the far left is 0% & on the far right of the slider is 100%. I slide that thing all over the place and don’t notice any difference in perceived effort or displayed power at a given cadence. 100% is just like 0%.
What is the purpose of the resistance slider? How do you use it?
