This makes it very hard to reason about or define any relative <br>
properties about Approval…</blockquote><div dir="auto"><br></div><div dir="auto">Not answerable without specifics.</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex" dir="auto"></blockquote><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex" dir="auto">though, because it kicks the can down the <br>

This is perhaps a bit exaggerated, but to show a point: does Approval <br>
really pass clone independence? Suppose more candidates of a wing show <br>
up, which embolden people to be more discerning than just approving <br>
what's acceptable. Then the winner changes.</blockquote><div dir="auto"><br></div><div dir="auto">I don’t know. It depends on how you define that criterion. Anyway, that’s entirely your business.
