BTW, I'm not arguing against McCready theory. However, I do think you
need to account for the overall conditions and things like TAS and
lift strength versus altitude, thermal centering time, winds an
proximity of turnpoints. Not all of those factors are accounted for in
the base theory and some of the outcomes are quite a bit more extreme
that you might expect.

See BB's analysis of upwind versus downwind turnpoints as an example.
Using that advice gained me something like 4 mph on a long task where
the first turn was into a 30 mph headwind.
