I do know that when my kids submitted ballots I got several where they
only played 5 games and rated four of them 1-4 and the fifth they rated
8th because they disliked it enough that they assumed the other games
would be more fun. When I submitted their ballots I took out those
"spaces" and simply submitted them as 1-5 since that was what I assumed
the balloting needed.
Was I wrong?
Not really wrong; ranked pairs can handle "I like A, then B, then C,
then anything else I didn't play, then Z", or even "I like A best, then B
and C are both good but I can't decide between them, then anything else I
didn't play, then Z".
Which you could write "A, B, C, NotA, Z" and "A, [B, C], NotA, Z" (where
NotA stands for None of the Above), respectively.
If they, or anyone, was certain they would prefer a game they hadn't
played over one of the ones they had, that can be done; but that that was
the case, and how to indicate that, wasn't made really clear for this
With that information, you can still get the marginal vote table, and
still get a RP winner.
(Really, you could think of your ballot as an 8x8 grid, and you can put
either a + or a - in each square, or leave it blank (then the marginal
vote table is just the sum off all the ballots) but I hope it's mostly
obvious to people how you would go from a ranked list to a +/- grid.)
