Nice posts, good reads.
It sounds like in that turn-n-burn you had with the spit in the evening you weren't using your flaps. If you're in another turning war and aren't going that fast, try experimenting with your flaps (it will help you turn better, but unfortunately slow you down and eat up whatever energy you might of had without using the flaps). Also keep an eye on your opponent's flaps, in a slow and tight turn-n-burn you should easily see if they got their flaps down or up. This is a good indicator on what your enemy is planning to do next, and knowing what your enemy is planning on doing next can give you the winning edge.
