Would anyone kindly provide some context for the less-informed like me? How fast can the top-of-the-line 4th gen fighters turn? What about the F-22? What about the Su-35?

It depends on altitude as well. The F-35 under some fuel loading conditions has been demonstrated to do a 30 deg/sec instantaneous turn, the F-16A is supposedly rated at 18/26 sustained / instantaneous (presumably near sea level). The Su-27 is reputed to have a max 22.5 sustained 28 instantaneous rates, while the Rafale's sustained turn rate is supposedly around 22 with an ITR of 30. The F-22 supposedly has a ridiculous 28 degree / sec STR, while its ITR is unknown (presumably very high due to TVC).
In 4th gen combat, ITR matters if you're doing a suicide turn to quickly target an opponent with a missile; since ITR drains energy, it means you'll become vulnerable to other aircraft afterwards. STR matters more for conventional dogfight maneuvering. In 5th gen combat, STR might not matter at all; dogfighting is suicide when everyone has HOBS missiles, while ITR could be useful for allowing you to reduce a missile's no-escape-zone; i.e, if it's BVR, and you're highly maneuverable, you're going to be harder to hit than an aircraft with lower ITR. That's why the F-35's STR is relatively mediocre but its ITR is good; once you get to dogfight-land maneuverability doesn't really matter anymore.

Yes, my point is that using videos to act as a lower limit makes sense, but then we shouldn't be surprised if one day we get videos of J-20 performing maneuvers in a manner which is greater than what current/previous videos show.
Which goes back to my original question about why do we think the J-20 clip in question is sped up -- i.e.: would such a degree of performance be considered unrealistic for the aircraft or compared to other aircraft in the world?
I understand that, but based on the accepted understanding that most J-20 videos show the aircraft performing likely well below its upper limit, then shouldn't we be expecting to eventually see videos of the aircraft performing in a more energetic or maneuvrable manner anyhow?

It's been a long time since I posted some eye candy, so here it goes...
As always, all images are high-resolution. Most, if not all, of the planes pictured are not new, but the photos were recently released, and as far as I can recall, have not been posted here before.

I believe these are old pictures right? I'm pretty sure I've seen all of them before.
If they are old (and not new), it is best to mention it otherwise people will interpret it as "new".
