The Net Wins are thus in a even- odd math pyramid related to Pascal's
triangle---
C = Number of Choices, W/L = Wins or Losses on each ballot (if each choice is
voted for in a different place)
C W/L Net Wins by Place
2 1 1 -1
3 3 2 0 -2
4 6 3 1 -1 -3
5 10 4 2 0 -2 -4
6 15 5 3 1 -1 -3 -5
etc. etc. etc.
The pyramid also suggests that a tiebreaker should be tried on cases
involving at least 4 or 5 choices (to see if it can collapse into a 3 choice
or 2 choice case).
The following--
22 ABCDE
21 BCDEA
20 CDEAB
19 DEABC
18 EABCD
100
produces a net wins table of--
A B C D E Total
A X 58 18 -20 -56 0
B -58 X 60 22 -14 10
C -18 -60 X 62 26 10
D 20 -22 -62 X 64 0
E 56 14 -26 -64 X -20
Tot 0 -10 -10 0 20 0
If the combinations of two versus the other three are done (such as BC versus
ADE), then the following results --
AB 10
AC 10
AD 0
AE -20
BC 20
BD 10
BE -10
CD 10
CE -10
DE -20
Total 0
Each combination amount is the sum of the individual totals from the net wins
table. The cross amounts cancel each other out (e.g. - A over B cancels
out B over A).
Thus, the highest combination of votes will prevail.
Example -- with 7 choices, the combination of three choices with the highest
total of net wins will prevail.
