What I basically meant was you want your drag force to increase as little and as slow as possible as the AOA increases so as to achieve a better lift-to-drag ratio.
It's really about hard evidence. So far I have only seen F-22 doing about the same STR in the videos that I have seen.

True, that's what I want to point to a few posts back, the paper that was posted said nothing about J-20's drag characteristics, it's a bit of an unknown so we can't say anything about J-20 STR performance based on that paper alone.
Fair enough

Not saying they are even but saying that there are cracks to America's propaganda that the Raptor is an alien bird that's best at everything, can out-maneuver a helicopter, etc...
But I'm not coming to the same conclusion. Americans are trying to conclude that if something is unproven then it's garbage. I'm saying that if it's unproven, don't assume it's the best or that it puts you at a disadvantage no matter what the enemy tells you or wants you to think. I've never concluded that J-20 was superior or inferior to a Raptor though I have my speculations about how they compare in various aspects.
Well that's very much fine as long as there is no misunderstanding. Both underestimating and overestimating your enemy can be equally deadly mistakes and I think that although the Chinese are generally meticulous and conserved, not prone to underestimation, we need to be careful not to make the opposite error either.
Yeah, not only is the plane in high AoA it is also in high side slip as well

You've confused me with someone else making up numbers. I'm the one saying that we don't know enough about J-20, F-22 or any other 5th gen to be trying to analyze one over the other. I said that in exercise, the Raptor didn't always come out on top in certain envelopes against 4th gens, which is fact. And I certainly wouldn't assume an edge for the Raptor built to counter 4th gen platforms with all rival platforms built to counter it.
It's true that we don't know, but that's why we don't believe the hype. The point he's making is just because we don't know the Raptor's performance parameters doesn't mean we should buy that it redefines physics.
So... specs or it didn't happen.
With all these discussion about flight performance, it seems to be only really relevant when the planes enter dog fighting range which is a big no no in modern air doctrine, I believe that the most important aspect for any 5th gen aircraft is frontal RCS, radar, range and sensor fusion , everything else including dog fighting should be set aside as duels would occur far beyond visual range, so there's no need to get too hung up on the flight performance between f-22 and J-20, only supercruise is important as it means faster time to intercept and longer legs.
Yes. There are capabilities of the Raptor not displayed to the public. Despite its age it is a very potent platform, otherwise Japan and Israel wouldn't have wanted to import it (but were rejected for national security purposes).
