FTP disaster test correction factor

I’m a pretty explosive rider, and I know that the FTPs from my ramp tests are a bit too high. So I need to adjust them down a bit to set my zones correctly.

A 20-minute test obviously provides a better assessment, but the problem with that is: 1. I really hate doing it, and 2. the consistency is much lower than with my ramp tests.

So I prefer to use ramp tests to regularly adjust my zones (which Join, of course, asks me to do), using a correction factor (or “bias,” if that sounds better) that I validate every now and then with a 20-minute test.

Join just doesn’t like it when I do that after a ramp test, and immediately lowers my accuracy level.

Sooo: a ramp test bias factor, please 🙏.

Thanks in advance!
