Seafire brings up a good point. His load is stiffer than mine by a couple tenths, but Blue Dot likes to be run "firmly." It likes to be on "the cam" on the sweet spot of your (and yours only) pressure curve. If you really want to get the most out of Blue Dot, you should have a chronograph and park your charge weight just below the point where speed increases start to flatten. It's a narrow plateau, but a good one.
