Proposed change:
A.6.3 Any (non-default) option which does not defeat the default option
by its required majority ratio is dropped from consideration.
a. Given two options A and B, V(A,B) is the number of voters who
prefer option A over option B.
b. An option A defeats the default option D by a majority ratio N, if
V(A,D) is strictly greater than N * V(D,A).
c. If a supermajority of S:1 is required for A, its majority ratio is
S; otherwise, its majority ratio is 1.
Two options plus default option. 400 eligible voters. Quorum of 30. 75
voters.
75 ABD
A wins easily.
75 more voters.
75 BDA
as per A.6.c, the required majority ratio for A is 1.
per A.6.b, V(A,D) > V(D,A) must be true lest A be dropped from
consideration. V(A,D)=75; V(D,A)=76. A gets dropped from consideration.
so we see that by simply doubling the number of voters, we can cause an
otherwise winning option to be discarded. this has the same effect as
A.6.2.
