The math of reversals shows up especially with 4 or more choices.
4 choices
24 combinations
The sum of the votes in the first 2 places of all of the votes may or may not
be a majority for a choice.
If reversed, then any majorities would be minorities.
Throw in some clones (from 100 percent to bare majority) and more *strange*
stuff happens.
I mention again that when a third choice is added to two existing choices,
such third choice may beat 2, 1 or 0 of the two original choices --- which
shows up in the various tests of the various election methods -- i.e. Any
method will have some sort of defect -- or, in other words -- see Mr. Arrow's
observations.
