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

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"?
