Yes. I called it "Gradual Info Approval," though.

Interestingly, I tried the scenario which needs no introduction:

49 A
24 B
27 C>B

in IRNR, and it seemed to me that in order to get A elected, either
the second faction needs to be unusually small, or the third faction's
score for B needs to be unusually low. Both would help.

I also had difficulty creating a scenario where the A voters use
offensive strategy by propping up C. If C isn't *expected* to do as
well as B, then the A voters will have to sacrifice a *lot* of points
to get B to be eliminated first. That's obviously risky.

Hopefully someone else can find an egregious IRNR failure.
