You can exaggerate weak era claims, but the fact is, you still missed your guess by 7 slams even allowing for luck for Djokovic to reach a mere 4 instead of the 11 he got. Missing a guess by 7 slams, 7!, the entire career of a McEnroe or Wilander, just means that Djokovic vastly, vastly outperformed your estimation of him. But when that happens, it can't remotely be because you underestimated Djokovic. It has to be that his competition just kept getting worse even as clear ATGs like Alcaraz and Sinner have arisen.
Stats don't tell the whole story. The Borg-McEnroe 1980 Wimbledon final for decades was widely seen as the greatest tennis match of all time and was even turned into a movie, but it was filled with unforced errors. Now look at the most liked comments from the Cincy match:

"Probably the greatest non-slam final I've watched, just unbelievable." - 8,100 likes
"What a match this was. Alcaraz v Nole probably the best fixture in any sport right now." - 2,500 likes
"As an Alcaraz fan, how Djokovic came back after struggling so much with the heat is insane, legend." - 1,500 likes
"There is no one better in adversity than one, Novak Djokovic. Astounding feat of grit and determination. Wow." - 1,500 likes
"I don't think people realize how absurd it is for Novak to still be playing at such a high level at his age, and still winning major trophies against another generation of athletes." - 1,300 likes
"Match was amazing" - 1,200 likes
"It's unbelievable that a man like Alcaraz has come along and he's being able to push Djokovic beyond limits he has probably not touched before. Seriously, this was the greatest 3-set non-slam final in history. The level has been raised like never before." - 1,000 likes
This video has 7.8 million views. If the match was so awful, surely someone, anyone would have chimed in and said so, but none, zero, of the top-voted comments state this was a poorly played match. I mean, I know you know more about tennis than anyone on Earth and so everyone else's opinions are invalidated just because you say so, but I guess thousands of people who watched this match don't know anything about tennis or reality and are just lying to themselves.
Outside of 2006, Blake has never had any sustained level of play to equal to, much less surpass Medvedev, Zverez, or Tsitsipas, but all of a sudden #39 James Blake whose ranking would continue to drop the rest of 2004 is a "brutal" matchup, but Medvedev, Zverez, or Tsitsipas are all mugs. If that's not a self-serving agenda, there is no such thing.
Not proof. You're just asserting what needs to be proved and the assertion by itself has no merit. As to your objection to my objection of hypothetical matchups, you clearly didn't understand any of what I wrote.
