Do you know where I can find examples of these performance
differences? Specifically re: beatpath vs ranked pairs. I haven't
been able to find anything on the wiki.
Steve Eppeley has a version of Ranked Pairs called "maximize affirmed majorities", and he compares it to Schulze's method in detail here:

Why has Woodall's "symmetric completion" not garnered more attention
as a method for handling truncated ballots? Is there an argument
against it? I've been trying to study the idea that ballots can be
used to determine the relatedness of the candidates, and symmetric
completion is such an obvious idea from that perspective that I have a
hard time understanding the value of the "margins/winning votes"
debate.
"symmetric completion" = margins, in all ways. They are precisely equivalent. It has all the pretty mathematical properties, and associated drastic strategic burying needs, that margins does. Winning votes is a separate animal, and allows for less drastic strategy.
