Hi,
I use the workouts feature a lot during winter season and most of my workouts are Power-based, relying on %FTP for intervals. Right now, it is possible for the Target section to define a PowerZone, whether it is a predefined power zone (z1-z7) or a custom one. During winter season, I'm trying to improve my FTP and since I am using a custom power zone, I need to tweak it everytime my FTP changes. Having the option of using %FTP for a power zone (for example, such a PowerZone could be: [80% FTP - 90% FTP]) would be great.
Thanks!
