Let us compare three ways of counting this exact vote:
1) ``Classic'' Condorcet/Cloneproff SSD, with no quota requirements.
2) The newly proposed scenario.
3) The amended proposed.

under Classic method, Red does win.
under the proposed method, there is no vote.
under the amended proposition, Red wins.

the proposal brings the Quorum voting method back to the Condorcet
standard, while ensuring that a few developers (less that R) cannot make
any ``stealth decisions''.

those 8 people did not establish a priority between the remainder, and
as such, were indiferent to the results. if any one of them had marked
red below the rest,, such as 1222222322, then all the colours would have

this is what the voters had prefered. i fail to see the problem.

if you desire more buy-in, change the quota as required. 3*1/2sqrt(100)
is 15.

let us again consider this under the three methods, Classic, Proposed,
and Amended.

         Classic:   Proposed:   Amended:
1- x23    A wins     No Vote     No Vote
-1 x21

1- x23    A wins     No Vote     A wins
-1 x22

1- x23    B wins     No Vote     B wins
-1 x24

we can plainly see that the amended version prevents a few voters to
make a decision for the whole, but does allow for the will of sufficient
voters to be made.

If this were the case. However, there was no changing the order of vote.
the amendment maintains the Monotonicity Criterion. unless, of course,
you consider casting a new vote the same as changing an existing one.
