How about power profile & repeatability?
I measured repeatability as equal rest repeats. E.g., for 30 seconds, the 1 repeat is just max 30sec power on the ride, for 2 repeats it’s max 30 on 30 off 30 on, only counting the on parts towards the average.
I think this sums up the complete picture, or maybe I’ve lost my mind. Progression levels are on here: if your FTP is 300 and your sweet spot progression level is 6, that means you can do 3x20 at sweet spot (at 90% difficulty - rated very hard), and that’s on the graph here (albeit you wouldn’t take 20 minute rests).
The graph is from my workout today, which was 5x10 sweet spot, so you can see the shelfs at 10min (and nothing special at shorter lengths).

OK - So this is exactly what I have proposed before and is NOT the same as has just been introduced with the power record curve.
If one assumes that you could more or less mimic what Stryd is doing for running with power, then all it takes is a couple of all out tests at pretty short durations - eg. 3 min / 9 min / 20 min. And then Trainerroad can create a model for the entire power-duration curve that would enable one to have an estimate of how much power could be produced for a give duration providing a reasonable starting point for a race planning strategy. It is much more helpful than any single FTP number whatever that number may be.
Then people will say - why not just do the all out test for the race duration to see what you are capable of. But that is the whole point - I don’t want to do that!!! I never want to go all out during training plans. I save all out for racing. And also, isn’t that one of Trainerroads selling points, that it is no FTP test is needed as AI will do a better estimation. (I know it contradicts my statement about the 3/9/20 minutes tests from above - but in my defense, even Stryd has implemented auto calibrated CP)
