Welcome to The Sufferfest @newbie! First off, you’ve put out some very impressive numbers. That being said, with the information that you presented there are a couple of things to consider. First, we have two different fitness tests - Full Frontal (which you did) and Half Monty (which is a ramp, followed by a heart rate constrained 20-minute Tempo effort which is used to calculate FTP).
Your pacing strategy during the 5-minute MAP test could also impact your results beyond just the absolute power that you produced. As you mentioned, you hit nearly 8% higher than your previous 5-minute best power…and that’s a BIG jump! Also, if the first half of the 5-minute effort was even higher and your power faded over the course of the rest of the 5-minutes, you’d likely not be able to recover in time to put out an appropriate FTP power. We’re not firm believers in the 95% of 20-minute power because there’s a lot of variability in actually how far above FTP different riders can push in a fresh 20-minute effort. Based on the 1-hour power that you have produced, though, I would say that bumping up your FTP to that value in the app manually could be appropriate.

Hope that helps. Happy riding & racing! Neal
