I don't think "strong defeat" works well, since it sounds like an "it is or it isn't"
proposition, rather than a number of votes.

I think the answer for AWP is no. All these methods using WA are the same probably
because any given candidate's wins are all of the same strength. That isn't true
with AWP.

An interesting question: What if all one's *losses* are the same strength? Same
result?
