Thanks Barry: It's a system for sure. Your experience mirrors mine.
Watching performance ceilings decrease with age, with the personal exertion experience metrics changing,
I wanted to quantitate my performance for comparison to age norms and see if it might be a tool in training.


There is a lot of support for intervals helping, and it's been a challenge translating them to my capacity.
The FTP seems weighted as a proxy for mVO2, with stage advancement shorter ramp protocols useful,
as hour long tests seem useful in more advanced training where that level of exertion is just part of the game.
The engineer in me appreciates the science in it, but also the practical.
This stuff is useful in geriatric fitness, it just takes tweaking. It's a growing need.

Hammerhead got this rolling for me, when they started importing Workouts from TR, but they continue to be, um, a work in progress.
