If the FTP in Zwift is not the same as TrainingPeaks ... the workout will not be done at the correct resistance.

I am asking that the .zwo file created by TP in the workout builder include discrete data (FTP THRESHOLD) where Zwift will parse this and update the users profile.

If this number is not the same in TP and Zwift, what's the point?

The workout will have been done at the wrong resistance.

This will make the experience seamless and streamlined.
