I've never totally liked the percent FTP descrpition. Its useful post ride. But I struggle to relate to itwhile riding.

So I think of it more as interval time.

So your FTP is 60min pace.
I think of sweetspot as 30min pace.

I can feel what a 1min effort should feel like. What a 5 min effort should feel like etc. But I cant sit on a turbo and think 'hmmmmmm this is 88%FTP'.

You can look at your max powers for different interval lengths on TR, and compare them to your FTP to get back to %FTPs.

Don't get me wrong, I'm not there killing myself working out if I'm at 95%. Just that when I choose a workout I will look at where the intervals are in relation to my numbers. Normally I wouldn't care that much, but trying to balance work with training that doesn't tip me over the edge is important at the moment.

Also, your comment about the fly wheel smoothing out virtual power is interesting. How do the numbers compare in terms of accuracy?
