I see that people seem to be pushing the Wahoo App for spindowns. I have not had good luck with the App and find it generally, well, shite. So, I do the spindown through Zwift, after a ten minute warmup, done after logging onto. Sometimes, when I start the spindown, the resistance drops to the point where I am spinning out and the speed shoots up past 23 mph. Other times, it feels like I am going up hill, having to put much more effort to get to 23 mph. It occurred to me that Zwift might have me on a course, even though I havent gotten to the point of even selecting one.
Any answers or thoughts?
