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.

Thanks for your feedback.
For Bühlmann there are multiple models :
* number of tissue compartments (8, 12 or 16)
* A/B/C variants (at least for ZHL-16): A is theoretical only, B is for tables generation and C is for dive computer (more conservative).
So, we could implement those variants.
