Partial answer to Jame Vincent and Mark Geleskie:
The new Navy tables are not modfications to the old table, but a somewhat
new approach to tables. The tables were designed by Naval Medical Research
Institute (NMRI) to add conservatism, and allow for greater risk when so
warrented. The basic table is based on a DCS rate of 1% when used to the
table limits. For higher mission-critical needs, a 5% DCS rate table has
been prepared. These tables make to old table *look* like a 3% DCS rate
table. The tables were supposidly distributed (promulgated in the Navy)
through NAVSEA last spring/early summer.
If you can print PstScript, following is a graph comparing the NDL's for
the NMRI 1% and 5% tables with the PADI RDP. The upper curve is NMRI 5%,
middle PADI, and lower NMRI 1%.
This is not the definitive answer, but may interest some.
