[EM] A better between-frontrunners approval cutoff. Typo.

[MIKE OSSIPOFF]

First the typo:

I said that the expectation for the election is Pw*Uw + Pb*Uw

Of course I meant Pw*Uw + Pb*Ub.

A better between-frontrunners approval cutoff for when good numerical
information isn't available:

"I feel that the worse (or better) frontrunner is a little more likely to outpoll
the other frontrunner, and so I'll put the approval cutoff a little (correspondingly)
closer to that slightly more win-likely frontrunner."

Of course, the placement of the approval cutoff is done purely intuitively, according
to how much more winnable one frontrunner seems. If one feels twice as likely to
outpoll the other, then put the approval cutoff twice as close to hir. 

It's done intuitively, by feel, rather than numerically.

Or:

I don't have a feel for which frontrunner is more likely to outpoll the other,
and so I'll put the approval cutoff halfway between their merits.

By the way, for Score-Voting balloting, I like the slider-placement balloting, which
is perceptual and intuitive instead of numerical.
