As far as I have understood Manoj's May 15 proposal correctly,
an option is dropped unless it _directly_ defeats the default
option with the required quorum. I suggest that it should be
sufficient that this option _transitively_ defeats the default
option with the required quorum.
In Situation 1 in my last mail, the quorum is 38. According
to Manoj's May 15 proposal, candidate D is disqualified since
only 24 voters strictly prefer candidate D to candidate C.
According to my proposal, candidate D is not disqualified
since 38 voters strictly prefer candidate E to candidate C
and 42 voters strictly prefer candidate D to candidate E.
Manoj's May 15 proposal would choose candidate E. In the next
elections, when candidate E is the default option, Manoj's
May 15 proposal would choose candidate D. My proposal would
choose candidate D immediately. In my opinion, the advantage
of my proposal is that it doesn't lead to unnecessarily
frequent changes of the status quo.
