I would wager my FTP is between 355 and 360 but I really haven't tested this year. GoldenCheetah says 360, but when I do ftp by feel I tend to settle in around 357-358. Earlier this week my 3x20 were just below 360, yesterday my by feel 1x29 was 352 with a higher NP due to rolling uphill, tight turns, and such, but I could have done more.
I wouldn't say my legs give out per se, it's just obvious that they fatigue more quickly than my lungs do. For example, 3x20 day didn't really feel like much aerobically but my legs were not so happy by the last interval. So I am trying to figure out how to get legs and lungs to fatigue at roughly the same rate, but maybe that's not really possible.
