Dan,

The new short version of your paper I also find opaque. Earlier you 
agreed with Andrew that

And then you told me that in this example

46 A
44 B>C
10 C

your  K-count method elects A.

C>A 54-46,   A>B  46-44,   B<C 44-10

Each candidate has only one "non-victory".  So then I take it then, 
using Andrew's version  the winner is C, because squaring the pairwise 
non-victory scores of  C44,  B46,  A54 doesn't change their order and 
C's is the smallest.

Obviously one of us has it wrong.

Chris
