EM list--

I've just received the message that I'm replying to, and so
there hasn't yet been an opportunity to check out the SD
nonmonotonicity example. If SD can be nonmonotonic under many-voter
conditions, that would certainly count against it as a public
proposal.

But now I'd just like to reply to the cycle-simplicity issue:

Blake said [defining Tideman's method]:

>You keep by selecting the victories one by one, and resolving that
>they will be reflected in the final ranking.  Eventually, however,
>you may reach a victory that contradicts the decisions you have
>previously made.  When this happens, you just ignore that victory and
>carry on the process with the others.

SD:

Drop the weakest defeat that contradicts other defeats.
Repeat till there's an unbeaten candidate.

***

SD's simplicity is undeniable.

I just wanted to show that SD can be worded avoiding mention
of cycles just as Tideman does.
