Am I substantially wrong about any of this? Ultimately, in real and practical
terms, it seems that done intelligently, Score Voting devolves into Approval
Voting, and Approval Voting devolves into Plurality Voting."
The idea is that some voters dislike feeling strategically pressured to vote
their sincere favourites below equal-top. With voters never needing to vote
their sincere favourites below equal-top, previous elections become a much
better indicator of which candidates are really "weak".
So I don't see compliance with the Favorite Betrayal Criterion as "pointless".
