Typical range of W' or anaerobic work capacity

[davidtinker]

I have been playing around with power models, W' depletion/recovery models and so on with the goal of estimating FTP and tracking changes in intervals.icu. One of the challenges is deciding if a power model is "any good". Just because you have 14m @321w on your recent power curve doesn't make that a max effort, maybe you just haven't gone flat out for 14m recently?

 

One of things I can do is to see if the W' and CP values for the model look "reasonable" based on past info for the athlete and typical ranges for other athletes.

 

Does anyone have any info on typical "good" ranges for W' for the 2 parameter, 3 parameter and extended (Golden Cheetah default) CP models?

Holy crap! I read that. I was feeling quite clever at first, but that didn’t last long....

Tx guys. I have implemented W'bal stuff (chart and using it to detect when your FTP might have gone up i.e. when you do something "impossible" for your current parameters), that was easy. The hard bit is coming up with good W' and CP values automatically.
