Yes, shorter NDLs will call for shorter surface intervals, but the difference in the compartment chosen to control the surface intervals had a much bigger effect. A compartment is considered to be washed out after 6 halftimes. If you went to the max on the Navy tables with the 120 minute compartment controlling it, you would wash out after a 12 hour surface interval. If you did the same thing with the PADI tables, you would wash out after 6 hours.
Makes me appreciate my computer.
