Of course, the other problem you'll run into using data points as your only "solid" evidence is that in manuals, to what I've seen, these points are only applicable to pilots/aircrews who would follow the manual to a T. Try calculating the F-14A's turn rate at 12.2G at 600kts. By the 1.1, you can't, but you'd better believe it happened (TACTS range recorded it in a fight vs an F-5E). What about at 10G to evade a SAM over the skies of Iraq during Desert Storm? Again, manual says "plane can't do that". It did. G-limiter pegged to get the hell outta the way. At times, like in the case of the 12.2G yank the objective was specifically to get slow quick, and get the Tiger off the Turkey's tail. End result was a slow speed rolling scissors which the F-5 was loosing after being on the offensive and unable to match the F-14's turn rate from the yank. KIO Deck was called before the Turkey driver called guns on the Tiger. Both the F-5 and F-14 drivers in the incident concur on that point. I use the F-14 in these examples, because it is a plane that I've researched; but the same must hold true for any other jet without hard limiters.
For that matter, those charts don't talk about fighting in the full three dimensions of air combat. What is the rudder performance at high versus low speed? Can the plane out-yaw another? How about spoilers or the horizontal tail coupled with the rudder and other surfaces? A common maneuver of Tomcat drivers in a slow fight against a more nimble plane was to use opposite stick to rudder, where at slow speeds, the airplane would generate a high yaw rate in the direction of the rudder/snap roll, keeping the plane's nose on the target, when the target aircraft thought it was getting away. Climb rate with or without flaps? What about at combat altitude? How does the jet perform outside of those envelopes, both on the high side, and on the low side? Clearly that's not going to be in there. A lot of this has to come from the folks who flew the jets, because they were pushing them beyond the envelope, outside of the area covered in the manuals.
I also continuously hear from pilots who "grew up" in the era before all-aspect heaters (Hoser, Turk, Hawk, Snort, and various pilots they flew with and against) that dogfights could commonly turn into slow-speed ordeals (even F-4 vs F-4), where the pilot with the better handling of his aircraft at such speeds (under 200kts), especially in a scissors (regardless of type vs. type, and executed time and again against smaller aircraft) would be the ones who came out on top. Today, that might not be as much the case, as most modern fighters at combat weight have better than 1:1 Thrust to Weight ratios (F-14B/D, F-15A/C, F-16C, MiG-29, etc.) and so can sustain energy better; but the idea that fights don't get slow, or that dragging an opponent to a slower speed than his own max performance speed doesn't happen seems ludicrous to me.
Even more, looking at the weapons systems of today, high off-boresight missiles have massively changed the dogfight; the first person to get the target within 60-degrees of the nose is going to have the first shot. It's quite a bit different now.
