[EM] medians and Heitzig's approval-voting strategy

My understanding of Weinstein's approval strategy is this:
"Approve your favourite (or equal favourites). If the remaining (so far 
unapproved) candidates are on more
than one of your preference-levels, then approve the candidate/s on your 
next-from-the-top  preference-level if
you consider that the probability that one of the candidates you prefer 
less than this/these candidate/s  will win
is greater than the probability that one of the candidates you prefer 
more will win.  And so on."

This strategy seems sane to me, and probably right for voters who only 
have a ranking.
