Also, it seems to me that if someone is ambidextrous they might be able to do about the same level of gripper closes with each hand.
I wouldn't think so. Its probably more of an issue of adaptation... Like this: I'm right handed (I assume you're right handed too) and so my right hand is adapted to doing all sorts of tasks. It works smoothly and effectively for things like writing, turning screws, etc. But my left hand has not made this adaptation, so if I try to write with it, it is awkward and real clumsy. I think the same applies to grippers, and that's why we recognize one hand as the "off-hand". It's the hand you don't use alot, so it's clumsy and can't quite recruit the same way as the "on-hand"... When I do grip lifts, like rolling thunder, both hands generally exhibit the same degree of strength, but when I do grippers, the difference is dramatic, and I believe it is related to this adaptation aspect.
