Of course

But do you disagree? You don’t think VA has improved a lot since 2017 when he would regularly run out of gas?
I don't want to have an argument with you, to be clear. And I'm sure VA has improved since 2017, but I don't think he has improved as much as people say after January 2020.
I just think whatever improvement Viktor has made (and the Denmark Open Final 2021 made me think it wasn't all that significant against a clearly weakened Momota), his "prime" coincides with the - by far - weakest MS era I've ever seen.
There is one (1!) world class player right now. Other established top players have either retired (SWH, CL, SHY, 2017 and '18 had a very nicely playing LCW in his second spring) or regressed (KM, CTC, ASG, JC, KS, AA) and the ones left are really young and/or inconsistent (LKY, LZJ, LS, KV). I don't really see how that's even debateable. The level of play is woeful with Viktor being the only one left performing great badminton (and the occasional good performance from LKY and LZ, but occasional is the key word here). That's been going on for over two years now.
There are now signs that Ginting might be slowly getting back on the horse, but currently (more or less the last two years) there has not been much reason to run out of gas for Vikor, as you call it. The opposition doesn't require it.
