[EM] average over time proportionality election method

[James Green-Armytage]

Hi there (Raph?)

	I think that it's a fun idea, and well thought-out, but can you think of
a practical application for it? Of course you wouldn't want to apply it to
executive elections, unless the executive authority was purely ceremonial.
If you did that, the most dangerous and bizarre ideologies would
eventually get a chance to run the country, which is obviously neither
desirable nor something that would maintain consensus. If you're using
this for legislative elections, in a fairly large legislature, then you
can argue that it's okay for the fringe ideologies to get represented
every now and again, because they'll be very unlikely to hold a majority
at any particular time. But if broad representation is your goal, why not
just use STV or some kind of proxy system? Using your proposal for a
legislature, the shift of power between different ideologies will
fluctuate with a fairly high degree of randomness, making it hard for the
majority to justify their authority.
