Of course, that despite the fact they were never intended for the use they were put to. NEDU Report 83-13 points out some errors of the USN tables, where some of the shallower exposures were shifted resulting in an underestimate of the 'rep group' for that exposure by one letter group. They also pointed out some typos for the SITs. Bove and Davis do not state that the tables are unsafe for those exposure. They project that they could be. The manner in which the Navy used those tables produced a hit rate of ca. 0.04%. Modifications of them (not in substance, format only) abound, the Nu-Way tables being one of them. Current and previous NAUI tables R truncated forms of the USN tables, with: 1. Shorter NDL's 2. A total 'clearance' time of 24 h 3. Bottom time calculated from surface to surface with safety stops being 'nul time'. The PADI RDP is a completely new 'dive table' system, where more 'Rep groups' are used, but the controlling compartment is a 60 min compartment instead of the 120 of the USN standard exposure tables. 240 for the USN exceptional exposure tables. Statistics do not show that the USN dive tables as used by the sport diving community resulted in an undue # of DCI cases. The # of cases reported to DAN have remained in the 400-500/annum range even with the transition of tables. I would be suprised that there is a true 'copyright' on US Government documents, especially since they are being made public without deriving any income for the publisher/circulator. In some circles the photocopying of copyrighted material is frowned upon. So all in all John, your outburst, other than being relatively baseless, was of an uncalled fervor. What purpose did it serve? You tell all that the technical diving community will not use them, so their availability should be of no consequence. Drugs are available, which is of no consequence to those who do not wish to partake in them. If others want to use them, I don't think it is anybody's business. Esat Atikkan
