Regarding (1), I'm not sure exactly what "the criterion’s premise’s 
stipulations about rankings" means.

Your point (2) is inadequate, because it could be that the voter intends 
to strictly rank some candidates while the actual
used method allows but not compels the voter to equal-rank them. By this 
definition it could be possible to create a
"criterion failure example" by having "actual votes" with equal-ranking 
where the voter intended strict ranking, even though
the the used method would have allowed the intended strict ranking.
