To Jim Cobb
Jim, You stated: " Shoot, half the fun of deco diving is doing the pre-dive
calculations.It up's the ante in that you are experimenting with your own
body finding
out what the best profile is for you. When you start getting indications of
your limitations, i.e. joint pain, slobitus, that tired feeling, fried
lungs,etc. you adjust the calculations until you are dialed in. I can't
imagine not having the ability to fine-tune your profile. "


So I guess then based on your statement , that there must be two types or
definitions of DIR

1. Doing It Right ( the one most people are familiar with)

2. or as someone else has stated instead Doing It Ridiculsly

Sounds like you follow the second one

So which DIR do you really support


Now to answer your last email

First: Do you guys ever read. I did not mention anything about my dives

Second: I will tell you I do not go out and bend myself on purpose just to
see what my threshold is on a given day, like you advocate

Third: You stated you deliberately bend yourself then back off. Now that
cannot be considered a logical or intelligent action.

Fourth: I would imagine many if not most divers who do a lot of deco dives
have had niggles

Fifth: I hope most of these people do not deliberately bend themselves
