I was joking. Almost everyone who quotes a number in the PM/training threads never tests so their figures are rubbish. Test your FTP is my stock answer for any question that mentions a PM. :)
But given the mileage he's riding, even if his ftp is a little off, it won't make much difference.
But my opinion is afyer 4 days of solid riding, the whole PMC thing just doesn't really work as intended. It can be useful, but you need to learn to read it differently.
I'd presume just before he started.
It's around 24tss/h. Which is about what I can manage fatigued.
