Ben, Why the confusion about no computer in DIR? Since most computers today are based on Haldanian compartment models, and DIR diving doesn't subscribe to this, then computers have no place in DIR. Furthermore computers would provide contradictory information that would have to be rejected in order to continue DIR diving, including unnecessary deco stops and safe time-to-fly recommendations far in excess of the three-hour standard practice interval used by George & Co. following deep deco dives. Also, the depth profile printouts that are so useful to personal-preference divers might suggest to DIR divers that modification of their ascent rates would help in future safe dive planning. In other words, computers are too safe and conservative to be considered useful in DIR diving. Convenient technological improvements like computers should have no place in DIR, obviously.
