Anything with a VI close to 1 will serve as a good indicator. VI of 1.27 is a lot of variability. Makes me thinks that you were riding in rolling terrain. Drilling it on the uphill and recovering on the downhill kind of ride. Not a very good test for aerobic strength because you're replenishing your anaerobic systems there as well. That said, your FTP is still set pretty low.
Yeah, everything around here is hilly unfortunately which means any testing I do is inside. 20' avg was 222 and NP was 292 with a VI of 1.32. I guess for now I'll just adjust my FTP value until my 60 minute NP is near 1.0 and go from there until I can test. Thanks for the feedback.
