On the Swim Smooth Guru site they have CSS Tweaker functionality (CSS is the swimming equivalent of FTP) - this prompts you to select how you felt after each CSS session (“Off-day”, “Bold”, “Heroic” etc.)… this then tweaks your CSS continually throughout the course of a plan. So instead of only testing every 6 weeks as before, the workout intensity is constantly adjusting to any improvements in fitness.
It struck me that this would lend itself really well to TR… after every relevant workout the TR software would prompt you to see how you coped with the workout - based on this, the software would make minor tweaks to your FTP. The ramp test didn’t give you a true FTP estimation? Not a problem; over the course of a few weeks it’ll be adjusted to a level that’s optimal to you.
I know there’s already the option to manually adjust FTP, but I don’t think that’s something that many people are using (looking at many of the posts on this forum). With the TR software actively prompting for your feedback after specific workouts I think everyone would end up with their FTP at a better level.
There’s been talk on here regarding adjusting FTP based on machine learning algorithms, but I personally think you can’t beat user feedback.
