Couldn’t have said it better. TR (Nate and John) have a way of belaboring how difficult and mentally stressful an FTP test is, and that a ramp test mitigates this, but in my experience there are VO2 max and anaerobic workouts that scare me far worse than an FTP test. I’ve only done 2 of Kolie Moore’s FTP/TTE progressions, and neither were stressful. Both were excellent workouts and left me with higher than expected power/TTE numbers. I’ve actually “failed” more ramp tests.
That said, I do think that the ramp test can be a “good enough” solution for a big base of TR users.
However, only if they are willing to adjust future workouts to compensate for potential over-testing, which I suspect happens fairly often. This is something that you don’t have to acccount for with a longer FTP test.
