It occurs to me that this method is very similar to the method Chris
recently brought up in a response to me. (I can't see Chris' posts unless
they are forwarded to me, so perhaps this was already noticed.)

The difference is that Chris' suggestion doesn't have rule #2, and in
rule #3 the reweight is to 0.

So with respect to incentive to bullet-vote... Rule #2 seems to hurt the
situation compared to under Chris' method.

I have the same general concern that if you approve your compromise 
candidate, who ends up being the most approved, you can weaken your votes 
for your favorite candidate and cause him to fail to qualify for the 
second round.
