On top of that, you then have to consider the potentially lower popularity of your favourite choice against that of the current lead contenders. Do you reduce your vote for the better of two evils so that your sincere preference has a better chance? Ugh.
I'm not trying to suggest tactical voting doesn't exist in other systems, but to suggest that it doesn't in Range voting is either misinformed or disingenuous.
With approval voting I have to make that decision, setting some kind of threshold of approval. With range voting it might be easier to just vote honestly.
At worst, everybody votes tactically and you get approval voting, which is still a good system. But sometimes the tactical decision is difficult, in which case range voting gives you the option of just voting honestly.
It's a good thing I didn't suggest it, then.
