Recalculate Progression? Can't set manually my FTP.

I’m trying to manually set my Treshold, but whenever I enter some values and click recalculate progression, Xert sets my FTP somewhere in range of 250-350 W and 4 min w/kg (puncheur setting) in the 5-17W/g ballpark. Am I doing something wrong or how can I manually set my FTP? I did some ramp test protocol, for my latest test, rather than steady state effort and I am sure that my result is correct.

Follow the instructions on the FAQ on how to recalculation your progression (you should save the signature first). Alternatively, you can open your ramp test activity details page and manually set the signature and Save/Lock to have this change reflected in all future activities.
