Power Truncation: If the voter chooses the power truncation option, then any candidate whom s/he doesn't rank will be scored as if that voter has ranked every one of the other voters over that candidate. In other words, that voter is opting to increase the greatest votes-against of every candidate whom s/he doesn't rank. [end of power truncation definition]
Did you really mean to write "ranked..other *voters*...over that candidate."? Should "voters" read "candidates"?
Regarding this example, do you agree with the way Kevin Venzke has scored MMPO with Power Truncation?
49 A 24 B 27 C>B
A wins (51 votes opposition from B or C), and B does the worst (76 votes opposition from C). I think this will force C voters to rank C=B.
According to my interpretation, the only effect of PT here is to raise C's score from 49 to 73, only changing the result from a BC tie to B winning decisively.
Would any voters ever have any incentive to *not* use "Power Truncation"? Chris Benham ---- Election-methods mailing list - see http://electorama.com/em for list info
