OK please tell me per my observations where I am confusing maneuverability and the inertia held by the a/c? To be clear my point is you dive the brew breaks down and turns , You pass the brew about co alt after dive and begin a climb back up[(but not to sharp) the brew continues his break until he has turned back to you and begins his climb and actually succeeds in closing distance. I saw that is maintaining E that he gathered during his downward break but maintained it through the turn and eventual climb. That's E management not manurverability. IMHO Then again I really dont care If Karnak took the time to verify then Ill accept his findings but at this point you just want to argue semantics. Im not even sure you got the rigth guy's 'obsevations'
For example, more maneuverable/pursuing aircraft can cut a corner on you as you are maneuvering and therefore it needs to travel a shorter distance than you in order to stay in a position where that particular aircraft/pilot desires to be. As far as the guns go, .50cal can be fired to fairly long distances accurately so the aircraft you are flying can be already clearly out running the Brewster but your plane isn't able to out run the .50cal projectiles. Also, from your posts it is fairly clear that you could have been clearly underestimating the e-state of the Brewster.
The above combination obviously causes an illusion where you think Brewster maintains and gathers E faster than you think it should while it is actually the above factors at work.
The definition of "E" here is, as I understand it, kinetic energy+potential energy. At mid altitudes, Brewster is the slowest fighter in the game with the I-16. That alone tells it is hardly an "E machine" of any sort since it can only sustain very low airspeeds.
These claims generally come from the fact that even a short time with guns on ones six can feel like an eternity.
If you think something is wrong, post a film about it.
