You make a good point. My main objection is that you can’t read the number as it flashes bye. So it’s not fit for purpose. If it updated at least I’d know the number!!! Lesson learnt, won’t be using this protocol to determine ftp in future.

You can just manually change your FTP in Zwift settings based on the result if you’re trying to calculate a new FTP that is lower than previous. If it updated automatically every time you did the grade, then your FTP would “update” to a superficially low number if you did a zone 2 ride that went over the segment, for example.

Gotta say that’s poor. So you’re on your knees when you finish. Looking for a tiny number that flashes by isn’t easy. The use case I needed it for was to determine my ftp after recovering from injury. It’s always going to be lower so only updating it when it’s higher is, as I say poor. Also, if it is lower and it’s not changed then all future workouts are being done at the wrong level. Would suggest some rethinking.

It says it on the sign as you go through the KOM arch at the top. Then the game will update your FTP setting, if you tested higher than what you had set.

I also wasn’t given an FTP estimate. I finished the full climb and went down and finished the route too.

I went up by 3.25 W/kgs, took me 17:51. A bit strange to Frank’s result. I’m 66 kgs only. First half I did about 2.75, second about 3.75. Does that make such a difference? Rode the Tron, too.

I spun up on the Tron at 3.5 and it was 15 mins
