Joshua,

The wording is correct and the English seems plain to me.

You just keep eliminating the candidate that has (among remaining 
candidates) the worst (as measured by losing votes) pairwise loss.

49 A
24 B
27 C>B

A>C 49-27,   C>B 27-24,   B>A 51>49

The worst loss (as measured by losing votes) is B's (to C) so we 
eliminate B and then A  (as Forest put it) "is undefeated among those 
still in play" so A wins.

Like Hare and Benham it fails Mono-raise and I think I eventually 
concluded that it was more vulnerable to Push-over strategy than them.

It has the advantage of being super-simple and only needing the 
information in the pairwise matrix.  It's alternative name is 
Raynaud(Gross Loser).

In the example I gave above, the three different versions of Raynaud all 
elect different winners.

The worst loss by Winning Votes is A's so that elects C (in defiance of 
the Plurality criterion) and the worst by Margins is C's so that elects B.
