Have you tested against a dual sided power meter / crank based / accurate trainer? I used precision, when I should’ve said accuracy.
For example ... I’ve seen when folks sprint they typically have higher degrees of power imbalance than steady state efforts, and then that’s slightly more imbalanced than a noodle pace
So if on sprints you’re 54/46 and then steady state you’re 50/50... any extrapolation or power curve will be off
Yah?
My Kickr 1 by most reviewers including DCRainmaker is 95+% accurate. It lines up extremely well with both my duos when it is warmed up as I mentioned,
As for accuracy, it's hard for me to believe my accuracy is off when all 3 separate devices line up nearly identically (and the Faveros to the freaking watt!). Having multiple devices that read the same is a pretty good sign of accuracy.
There is no way at all that my Unos are more than 10 watts off in precision (5%). I would notice that immediately. To even get a +5 watt increase in my ride averages requires a noticeable increase in average effort, every time. And for FTP tests, it's literally down to the watt. 1-2 at most. As said, I wish it would from time to time give me +5 on that FTP just to make me feel better, but nope. Literally +/- 1, MAYBE +/-2, but that's it. +5 FTP is like hallelujah land for me, really!
