Aero/tt vs upright ramp test

Say I do Joe Friels ftp test, which is 30 min solo all out and taking that average as your ftp, and I average 355 watts.
Then I do a TR ramp test and because there is so much time going beyond ftp 120, 130%+, which is not something that happens in TT’s I get a result that says 330 watts.

What test result should I use? If I use the TR test method I’m training 25 watts lower then where I should be.

Ramp tests can be a good method if using road bikes/sitting upright, but for an aero tt test I don’t believe it’s the best method.
