+1. I am a (low) 4.0, as are most ladies with whom I partner. When we play two 3.5s, our goal is to give up no more than three games. A double-bagel would be nice, but it is rare. All it takes is a lapse in concentration or a bad patch by one of us and they will get a couple of games. Lose to two 3.5 players? I don't think this has happened since I became a 4.0.
