The Buhlmann approach is well defined and all the details of his models 
are explained in his papers and books. However, the more modern dual 
state models (="bubble models") are mostly proprietary and all the 
details have not been exposed. For insance the variable permiability 
model is totally proprietary and people actually make money from it 
(e.g. VPlanner). Therefore they do not wish to expose the details of 
these models. The RGBM is the best described and understood but even all 
its details have not been published.
