The system, Binomial STV, which Kristofer once asked me to show how it 
works, with his example, is a statistical count, as the name, binomial 
Binomial Transferable Voting (BTV) is a generalisation from conventional 
STV, which is zero order BTV, which I support, because it is essentially 
the right method, unlike the legion of other official systems.
BTV is not a Condorcet pairing system.
