I suggest that a vote is "counted" if the voter doesn't wish he had
voted some other way.

In a Plurality election, the votes for a spoiler candidate are not
counted.

In an IRV election:

8 A>B
5 B>A
7 C>B

A wins.  The C>B votes are not counted.

Approval election:

55 AB (sincere preference A>B)
45 B

B wins.  Some portion of the 55 votes are not counted.  (That seems
intuitively wrong, but I'm not sure why.)

Schulze or RP election:

40 A>B>C
35 B>C>A
25 C>A>B

A wins.  The 35 votes are not counted.

By this definition, no method will be perfect, of course.
