Hi George, full disclosure I am a long time user of Zwift. I tried TPV / Indievelo for the first time yesterday: Very impressive, fully satisfied with the app, interface with TP worked fine (download and upload), congratulations for the good work.

For your consideration, I am sharing with you one feature that I believe would be a great addition to your product. It would be great if we could track the W' decreases and increases, particularly when doing intervals, with the goals 1) to avoid over training when the W' is becoming empty; and 2) providing the users to properly tailor their HIIT workouts (both for work and recovery minutes).

Please don't hesitate to contact me should you would like to discuss this feature further. Best regards.
