I guess this example shows you didn't understand it. "I really want A to win" isn't a strategic consideration. It's a statement of sincere preference that clearly contradicts what you had just said about the sincere preferences. > Seemed simple, I was "exaggerating." > > But wait!

This example is unfortunate since with candidates with an average utility of .5, and no information on any candidates' viability, it doesn't matter strategically how you rate a candidate worth .5. Let's say B is only worth .4. Now strategically you should exaggerate and rate B 0. That's because on a single puny vote, it's inefficient to try to save some voting power to help B beat C when the same power could be helping A beat B for a greater improvement. You could also need to rate B as 0 if you do not believe that your last choice C has a good chance of winning. This is because spending your voting power to help B beat C is relatively pointless if C isn't going to win. Again, you have one puny vote; it's different if yours is the only ballot.
