One way to get an estimate of what is going on with multiple choices
(especially with the amount of cloning) is to combine the highest net wins
choice(s) with the lowest net wins choice(s) repeatedly (canceling out the
internal wins and losses by making the combination).
Example-
Net Wins
A 125
B -40
C 20
D 25
E -120
F 15
G -25
0
Combine A and E
AE 5
B -40
C 20
D 25
F 15
G -25
0
Combine B and D
AE 5
BD -15
C 20
F 15
G -25
0
Combine C and G
AE 5
BD -15
CG -5
F 15
0
Combine BD and F
AE 5
BDF 0
CG -5
Thus, there are 3 choices giving an estimate of the amount of cloning. The
above should be used to test computer results if there are a large number of
choices (in connection with truncated votes).
Note in a more "normal" case of a real large election, I would expect the
final math to much more skewed such as
Group 1 12
Group 2 2
Group 3 -14
Example- a simple 3 choice circular tie
35 ABC
34 BCA
31 CAB
Gross Net
66 AB 34 32 AB -32
69 BC 31 38 BC -38
65 CA 35 30 CA -30
A B C
A -- 32 -30 2
B -32 -- 38 6
C 30 -38 -- -8
