: @[[User:RobLa]]: It can't be converted to a -1/0/+1 Score system, no. (-1, 0, +1) is mathematically identical to (0, 1, 2), and that produces different results in a few of the elections, as I said in the Analysis section.
: It's not ''psychologically'' identical, though, [[w:Combined_approval_voting#Properties|as shown by Baujard et al]]. Explicitly voting "Oppose" is a form of negative voting, not just an abstention like it is under Approval. In standard Approval, you approve of some candidates, and leave the others blank, which can mean either disapproval or neutrality. It could be worded better.

@[[User:RobLa]]: I think it is mathematically equivalent to 2-level Score with Abstentions, though, so I don't think that part should be changed.
For example, if you had 5 ballots filled out:
A: Support
B: Support
C: Support
D: Neutral
E: Neutral
F: Oppose
and 4 filled out
A: Support
B: Neutral
C: Oppose
D: Neutral
E: Oppose
F: Oppose
Then the S/(S+O) would be:
A: 9/(9+0) = 100%
B: 5/(5+0) = 100%
C: 5/(5+4) = 55.5%
D: 0/(0+0) = 0%
E: 0/(0+4) = 0%
F: 0/(0+9) = 0%
If Support = 1, Oppose = 0, and Neutral = abstain, averaged score voting would produce:
A: (1+1+1+1+1 + 1+1+1+1)/9 = 100%
B: (1+1+1+1+1 )/5 = 100%
C: (1+1+1+1+1 + 0+0+0+0)/9 = 55.5%
D: ( )/0 = 0%
E: ( 0+0+0+0)/4 = 0%
F: (0+0+0+0+0 + 0+0+0+0)/9 = 0%
