How to get a w prime number

[Tobias]

Hi I currently have blank Watt prime number. is there some kind of test you recommend me to do. to get a estimate or how does it work?

Look on your /Power page - you should have a W’ number next to your eFTP. You can then copy this value into the /Settings page

W bal estimation method?

Curious and I couldn’t find this elsewhere on the site or forum after a quick search: How does the W’ estimate on the Power curve page work? Is it based on my previous/recent anaerobic efforts or “guessed” from my FTP based on some average relationship between FTP and W’?

edit: that estimated W` is not very useful if you haven’t fed the model w/the necessary max efforts. In my case, I’m coming back from an extended break and have not done max efforts. I can easily find myself w/a W`bal depletion exceeding my W` w/out having gone deep.
