Have you read this book yet?
https://wish4book.com/education/1141...d-edition.html The the use of best 20 minute power is a suggestion from this book.
It seems that you misunderstand me when I say the Garmin FTP estimate is arbitrary. I have no issue with the theory of using
best 20 min power to approximate FTP. But I wouldn't give someone a Garmin and tell them it has a feature that can estimate their FTP if they JRA without any ride protocol. That estimate is completely dependent on them riding under the right conditions to produce their best 20 min power, which is by definition
arbitrary (seriously, look it up). And for anyone who doesn't have an idea of how to pace a 20 min full on effort (serious time trialists and hill climb specialists fit this description, not), it's either worthless or worse.
