I know our timings aren't as good as X yet, but we may be able to do something similar in the actual DDC probing as well (use fast timings first, then fall back to robust ones if that fails) and get a double benefit. Have you looked at that at all? Either way, this one looks ok, so I'm ok with it as long as Dave is.
