I like it!

It reminds me of dyadic approval.

Notice that the last step (otherwise, elect the approval winner) can be
restated as "otherwise, flatten all of the remaining rankings except for
the approval cutoff itself, and elect the resulting ballot CW."

I'm not suggesting that it be defined that way, only to note the natural
consistency of the last step with the over all plan of flattening more and
more rankings at each step in search of a ballot CW.

It also reminds me of another method that we briefly explored in which
every ballot rank mark can be given a different strength as in


It could be called "ranked ranks."  Or using high resolution score ballots,
the number of chevrons in the ranking symbols would be proportional to the
score differences of adjacently rnked candidates.

Gradually flatten ranking symbols until there is a ballot CW based on the
remaining unflattened ranking symbols.
