@marcus-ogren Good point. The idea behind the Critical Score is to boost candidates with isolated support. It's possible that it goes too far, as you've highlighted. I just found that to sort of achieve the effect I was looking for, I would need a really big exponent for the Power Score.
I wonder how it all washes out in more realistic scenarios, but it's valid to consider someone putting themselves on the ballot and literally not telling anyone just to then score themselves 5 stars. Perhaps there's some kind of balancing that can be built in, but I suspect, on the general advice of James Quinn, that that would likely cause new problems.
