The plurality winner, under honesty, would be a tie between C1 and C5. Under strategy it would be C5. That's still better than electing a random winner. The VSR of random winner would be 0%, by definition.
Now set up sheet like this for yourself, and go in there punching in random values based on the rolls of dice or something. And see what the expected utility return is for plurality as compared to random selection (i.e. just averaging the utilities of all candidates).
