This is a common question for runners new to power and wanting to ensure an accurate Threshold Power.
You can use any of the three most commonly used models.
Why?
Your threshold is a โphase transitionโ over a narrow range of intensities, with lots of metabolic changes occurring at different rates and in parallel. And your Threshold Power is an intensity thatโs within (or close to) the phase transition.
In this context, any of the three most commonly used models can produce a usable Threshold Power.

The answer typically depends on the app youโre using to review your power metrics:
๐น Using WKO? Youโll most likely use auto-calculated FTP.
๐น Using Stryd PowerCenter? Youโll most likely use Auto-CP.
๐น Using another app? Youโll most likely use CP tests.

No.
Itโs likely that each will give a slightly different result, although the Threshold Power numbers are usually within 2-3% of each other.
And if you have multiple Threshold Power numbers to choose from, choose the lowest.
This means your training targets will err on the side of under-training, rather than the side of over-training (and an increased risk of injury).
