wow. you just don't listen. here we go again.
if there's a condorcet winner, then dsv will indeed act in your best
interest. but the problem is when there's a cycle, in which case dsv
will cycle infinitely, trying to improve each faction's result.
eventually, there has to be a cycle resolution system. so say x/y/z
are going in a cycle, and x is declared the winner of that resolution
now what does dsv do for the majority who prefers y to x? nothing!
it says, "sorry, i have to stop cycling and pick a winner."
that's when they wish they had lied and said that z was their
favorite, preventing the cycle, and getting their second choice
instead of their third.
bottom line: dsv = condorcet, and can be gamed. your next step, after
finally accepting this reality, is to understand why your subsequent
objection (that it is infeasible to game condorcet) is also wrong.
but let's go one step at a time.
