Agree with the consensus here. You won’t be constantly breaking power records throughout the plans, because the workouts are split into intervals so you can do more work. Although it’s nice to get power PRs in TR, I don’t use that as a measure of my progress. Whenever I get PRs in TR, it tends to be in the final few hard workouts of a block (Leconte, Baird Peak, Ansel Adams +4 spring to mind).
Outside on a hard solo ride, chaingang or KOM hunt, you’re way more likely to set PRs, as you’re more likely to be pushing unsustainably hard at times. Using a personal example - last year I did 102% FTP for 24 minutes to get a local KOM. I got it, I was pretty cooked, and I did nothing else useful on the bike that day (albeit I was less fit back then). In TR there are no workouts in the plans that are 24 mins at 102%, but there is 3 x 20 @ 95, 97, 99% (Galena +2). This workout might not give you any power PRs because I the 3 intervals are shorter and lower in power than the hard one I did once. However, (I’m not a coach so grain of salt time…) I’m pretty sure 60 mins accumulated of Z4 work are far more useful from an adaptation standpoint than 24 mins at 102%. This is where you derive benefit from TR.
So my advice is not to sweat about your power curve - as someone said earlier, it will naturally bump up and right as your fitness improves. Again in my case, I finally wiped that old ride off my power curve the other week when I did 2 x 30 @ 98% in a custom work block (even though it was a lower % of FTP, I still beat the old record comfortably because I have a higher FTP from TR).
If you’re hellbent on breaking PRs, then there’s no substitute for outdoor all out efforts if you have appropriate roads for it. There will be certain workouts in the library that you can add to your calendar ad hoc. Look at ‘Banner’ or the Ramp test for 5 mins, ‘Hour Record’ or ‘Unicorn +2’ for 60 mins, ‘Polar Bear +1’ or other long SST for 2 hours.
