I did some calculations on course deviations versus expected climb

Steve Sliwa wrote his thesis on this topic sometime back in the 1970s
IIRC. * *He used a bit more than junior high trig, but the conclusions
were similar. * The secret was deciding sooner than later that "street
b" would work better than "street a", which is exactly what we see
qualitatively in contests.

Turns out the article was published in the April 1981 Soaring
magazine. I have a complete set of Soaring from late 1960s ... with
the exception of .... April 1981??!! Well, it's probably in one of
the "reading rooms" in the house, but don't have the energy to sort
through the stacks right now. If anyone has an electronic copy of
the article I'd love to re-read it; it's been years.
