I'm asking about the '45 minutes for 40 moves plus 15 minutes for the rest, without increment' portions of the matches (for the quarter-finals, semi-finals and finals), which consisted of those and then clearly non-classical time controls such as 15+2, 3+2, armageddon, etc.
Here's what I understand:
According to FIDE '45 minutes for 40 moves plus 15 minutes for the rest, without increment' is 'slow rapid'.
Rapid is any game whose time controls (which may have increment and which may have time bonuses after a certain number of moves), when converted to X minutes for the whole game with no increment are s.t. 10 <= X < 60. Is this inequality indeed strict? Maybe 61 is classical but 60 is rapid?
'45 minutes for 40 moves plus 15 minutes for the rest, without increment' is converted to 60 minutes for the whole game without increment, the very minimum for classical time controls.
Question: What's going on? Why does FIDE says 45-for-40 + 15 afterwards is (slow) rapid not classical?
I mean...it really seems like a regular 60min + no increment game but you get the final quarter of time only after the 40th move. I notice there are even posts like When are we getting a World Chess960 Championship with classical time controls? But apparently we DID get?
Context: Actually, my next question is how FIDE can just drop the time controls to a different category (without some basis I mean like with the cases of Sergey and Fabi in the WCC's vs Magnus - the challengers only drew with Magnus so they had to suffer lower time controls. Wesley So did way more than draw and so there isn't quite basis) and call it the same WFRCC instead of like the rapid WFRCC. All this time I thought both the 2019 & 2022 WFRCC were rapid. I didn't know that even 60 minutes counts as classical. But I have to make sure that they're indeed different categories.
