that is what a lot of the discussion above is about. C00w is working on new methods to hop unhoppable pools. It works great for some, no so great for others. The debate above is about improving the methods. Obviously this is difficult as these pools were set up to not be hoppable. Most likely you have a worse connection to deepbit than you do for bclc. If you become concerned it is harming your rewards, then just disable the mine_deepbit pools, until the guys get the bugs worked out on the method.
