Chris,
	I'm quite interested in this, but would find it easier to understand your
critique of equal rankings IRV (whole) if you could give an example or two
illustrating the point above. 
	I did read your 45-20-8-27 example from your previous posting
[http://lists.electorama.com/pipermail/election-methods-electorama.com/2003-October/011089.html],
which indicates favorite betrayal incentive. I found it informative, but
not entirely damning. Any other critiques you might have of ERIRV whole or
fractional would be quite welcome. I do have the sense that I'm going over
territory that has already been covered, so I'm sorry for missing it the
first time around. I do find the topic interesting though, and if folks
can get me up to speed that would be great.

James
