I hope no one reads into this that a drysuit will significantly extend dexterity. I've been reading stuff trying to find quantification of dexterity info for Shawn's table (rather than his estimates). While I haven't found anything quantified in terms of time, there are several articles that qualify dexterity with temperature. One key point is that even though the forearm is protected and warm in a drysuit, and the key muscles for the hand are in the forearm, cold hands still lose dexterity in water. There are several factors that contribute to ease of motion in the hand. Joints become stiff, the nerves are affected (loss of sense of touch and therefore ability to sense position, grip etc) and so on. This prevents you from using your hands even though the muscles are warm. The key is - for cold water, you'd still need hand protection, like gloves, to extend your degree of and time of dexterity.
