FTP is like pornography - hard to define, but everyone knows it when they see (feel) it.
More seriously: like the notion of a renal threshold for glucose spillover in the urine, the notion of an FTP (and LT) is really just a mental convenience. That is, there is some "splay" in the physiological responses in the transition from sub-FTP to supra-FTP intensities of exercise. It is therefore mistaken thinking to try to tie FTP to an exact duration, as it leads to people to lose sight of the above fact. That it is also unnecessary is demonstrated by the fact that people got along just fine for years between when I first introduced the idea and when even Hunter and I got around to trying to put a definition down on paper (at the last-minute behest of the editor of our book).
