Well done!
Please add multiple FTP settings for different sports, as many of the TR workouts can be used with other sports/activities. (e.g. Reddit - Dive into anything)
I tried to help myself (did some sort of “cheating the system”) with doing the math before every workout and adjusting the the intensity. During the workout it worked well, but afterwards it was a bit ugly/tedious (charts looked bad/wrong and I had to adjust the FTP every time for every workout).
Edit: some bad typos
