I agree that Jones wins in Bucklin.

Woodall proposes a method called "Quota-Limited Trickle-Down" or "QLTD" which
seems to be equivalent to Bucklin, except that when there is a tie (i.e. two
candidates achieve a majority at the same stage), the winner is the one who needs
the smallest percentage of the last stage's votes in order to have a majority.
(Assuming I'm understanding it correctly.)  By that method, Jones wins, because he
needs only 2/25 of the second stage votes to have a majority, whereas Smith needs
over 2/3rds of them.

I wonder if Woodall's version is slightly better at reducing regret.
