For NDL diving you can pretty much play any game you want, whether to make any particular set of dive tables your gospel, and push their limits as far as you dare anecdotally. Worst case is that you would then earn a chamber ride. Make sure your DAN insurance is paid, first though.
For deco diving, you cannot take anything for granted nor delude yourself, however; the penalty then is paralysis or death. You must start with a fairly shallow (150 fsw) dive for a fairly short time (20 mins), and test whatever table or software you are using from that point on with your own unique body and all of its hidden biological flaws. The anecdote then becomes one of conservatism, not of pushing your limits. It also helps if you dive optimal gasses and extend your deco times.
It was my honor to hear from Thal offline about his own guarded reservations about USN tables at their extremes. And it was my pleasure to see Geoff backpedalling from his fantasy logic when the proof was in the pudding.
Anyone still seeking the holy grail of "scientific" tables without anecdote might as well be looking for the golden fleece as well. Dave, I think your heart is in the right place about following a conservative scientific catechism. I just do not believe there are any that exist which are valid. Certainly not across the board, not for everybody.
Maybe Thal is super-human and can get away with anything? So what? I'm not going to try it.
