From your post in FTP detection results thread https://www.trainerroad.com/forum/t/your-ai-ftp-detection-results/70285/9 you said:
I did a ramp test and it was 1W lower than the AI FTP prediction.
Folks, take that ramp test on the same day for a proper comparison.
I’m squarely in the camp that a ramp test result matching the FTPD should not be used as a validation. Nor should any other FTP estimatation method or test. Doesn’t mean these won’t often be close.
FTPD is all about trying to best set training intensity. Hard Stop.
My concern is that if we take the mindset that test results like you indicate are the standard of validation - rather than tracking what really matters, long term performance gains - we will distrust the approach just based on if it doesn’t match. And there are many reasons why that might occur that have nothing to do with its utility.
