I reviewed the jug fight again, and I see where that one really demonstrates what I was saying in regards to net thrust and relative E. At 0:34 we match altitude for an instant, which makes for a good snap shot of E states (Batfink 198mph, Murdr 109mph). Starting at our respective peak altitudes, Bat drops 1,200ft in his first 360, I drop 700ft in my first 360. During that time, I'm maintaining better thrust efficency (gaining relative E), which is a theme I continue, while at the same time trying to minimize his converting that energy advantage into angles. Angle and separation are my primary concern, and the thrust is just an after thought that I'll work if possible, but look at how the effect accumulates. By 1:14 when we match altitude again the speeds are (Batfink 134mph, Murdr 145), and that nearly 90mph speed deficit is gone, but neither of us have gained angles enough to "make the difference". By 1:48 when our altitudes align again it's (Batfink 109mph, Murdr 155), and I have both the energy and position to intercept his transition into the vertical.
The only reason I'm highlighting it is because it's a facet of "he is constantly altering his stance, very sublty", that's not very obvious.
