Your method does seem similar to Borda. Do you have any arguments as to why Binomial STV is
better than Borda? There's nothing really wrong with Borda in your view, is there?

Well, I don't know what that law is, but I don't feel that Borda-likes adequately address
spoilers. Whenever a voted majority favorite isn't elected, there will be a debate about
who spoiled it.

In what way could there be a preference cycle with two candidates? Can you show the ballots?
