by counting a ranking higher than default as a special vote. this is
what makes it hard to understand. it also opens up the avenue for
strategic voting via insincere voting.
example: quorum of 20, two ballots on the measure, plus the default
option. two major schools of thought: those that support option A, and
those that support option B. privately, each consider action on the item
better than no action, but the A supporters, being the smaller of the
two camps (10 members, vs the 15 members for B), really want their
measure to win. they, as a block, vote 132. the B supporters vote
sincerely, and vote 213.
using the rules as proposed by Manoj, option B would fail to make its
better-than-default quota (having only 15 of 20). option B would then be
dropped. A easily beats default, and thus A wins.
using a straight Condorcet, or even a Cloneproof SSD, option B would
win. my amendment restores that feature of Condorcet/Cloneproof SSD.

this is a strawman, because if <R people vote, then no option will
achieve the R+1>default per-item quota.

even if this were the case, if there were no quota requirements, as in a
straight Condorcet or Cloneproof SSD, the most preferred option would win
the purpose of quorum is to inhibit ``stealth decisions'' by only a few
developers. this purpose is met very well by the amended implementation
of quorum. quorum is not meant to change the winner of the vote.

i fail to see that argument.
