Lost Yoopers-
One has to know the basic Haldanian-based theories of decomprression diving before indulging in VPM oror RGBM. Those two are actualy based on it themselves, only take it further by implementing a lot of new factors into the equasions.
About technical diving- I don't think that GUE's methods are right for everyone. (btw-thanks for the links you gave me in emai, it was very interesting) For most people and their intentions the standard aproach, such IANTD's, is good enough, and in itself, it is good.
The implementation of deep stops is something tricky. Dual phased decompression is a new theory that takes it further, but for most technical divers, it is not nessessary. Teaching someone too much may be a as much as a problem as not teaching at all, becouse he can mix up things.
Diverl-
If you are already familiar with the basics of the haldanian based decompresion models, than you can go on and read the researches suplied by lost yoopers, otherwise, it may just confuse you. you can start by reading a manual for a dive-master level course, it usualy holds a thorough explanation of the basics of the haldanian theory. You must first understand well concepts such as "m-value", "half-tissu time", "critical tenssion" and such before starting with RGBM and VPM.
One last thing- In order to become a technical diver, you do not need to understand all of the above. In order to become a technical diver you need to be able to perform things that are based on it. To do a decompression dive, you must be able to use a table properly, but not to understand the mathematics behind it. That's up to you.
