Deep stop theory is relatively new and suggests that micro-bubble formation in the blood with nitrogen can be minimized by using stops that are one-half the depth of the maximum dive. The Suunto algorithm will take this into account and places stops at deeper levels than used in standard practice. Not sure it adds alot to safety, but it is a nice theory. Sure you could find threads on this board.
