Hmmm so problems I see are that everyone is different.
Which is why you have to take such individual difference into account when quantifying training using TSS, just as you would when using any other metric. Then again, since TSS is based on what you actually did pedal-stroke by pedal stroke and takes into account your current fitness, variation between individuals is less than when using, say, miles or hours.

A ride with same TSS scores will be different between riders and will be different for the same rider from day to day for a million and one reasons.
But not different enough that knowing TSS isn't still useful.

Problem with NP in that it's cool for training but bike racing isn't like that. Even TTs and Pursuits as the weather, course, track and many other factors affect the ride. Road racing isn't decided by the rider with the highest NP it's by the rider who can get to the NP the fastest or is better able to use their max power.
You could substitute plain ol' "power" into what you've written above, but you'd still be missing the point: the purpose of training is to enhance the physical attributes (fitness, skills) necessary for success in competition, which in cycling means maximizing one's power output (and minimizing one's aerodynamic drag and mass) across various durations. Analytical tools such as normalized power, or even a powermeter itself, are just aids to achieving this goal.

Problem with IF is you are applying a qualitative factor and claiming it's a quantitative system. May as well go back to using RPE.
What qualitative factor is that? IF is the ratio of normalized power to functional threshold power, both of which are quantitative measurements.
fergie said:
Problem with basing IF on threshold is what is threshold? 60min pace. Good for those people who can pace themselves. Many road racers can't pace themselves. Why 60min? Why not 58mins. Again you are basing a quantitative system on someone picking a mark in the sand.
And again you're throwing the baby out with the bathwater. Functional threshold power can be quantified numerous ways, all of which lead to comparable values. IOW, it doesn't matter whether you pick 58 min or 60 min, or rely on critical power testing, or base it on actual blood lactate measurements to determine maximal lactate steady state, the fact remains it is the single most important physiological determinant of endurance cycling performance. It therefore makes perfect sense to base a system around functional threshold power, as I have done.

That's enough for now I have to summoned to plan someone's training so better scoot. Argue amongst yourselves and get back to me!
Oh yes, the standard response on the internet when someone feels that they are losing a debate: "I'm an important person who has got more important things to do!"
