Walter:The PADI RDP is fairly liberal with respect to NDLs, but they are extremely liberal with respect to repetitive diving. It's likely the man is not referring to NDLs when he says the tables are too "liberal with their time frames."
Hi Walter:
I'm reminded of what my "Mix" Instructor told me about deco "theory" and the various deco schedules
This might not be and exact quote, but,........"Just about anything "reasonable" will work".
Of course this was in the context of proper ascent procedures etc.
One look at the various schedules produced by the same deco program with varying levels of "Conservatism" would confirm this.
I can't imagine a "table", made and used for millions of Rec divers would be much different than the next, and would probably be fairly conservative at any rate. "Well in the green" if you chose to use "dive computer" language
It's funny, but the more familiar I am with the program I'm using, and the more profiles I run, the more I am inclined to agree with the above statement by my Instructor.
