What is the most recent AIG (Advisory Information Guide) involved in phase 3 validation of decompression tables?

The most recent AIG involved in phase 3 validation of decompression tables is EDUG, or the Extended Decompression User Guide. This guide contains critical information relevant to the validation process of decompression tables, particularly focusing on extended time exposures and the effects of different diving environments and conditions. Understanding how this guide fits into the broader context of diving safety and the scientific principles behind decompression is crucial for SCUBA divers and supervisors. The EDUG is designed to enhance the knowledge and practices around safe ascent rates and decompression procedures, ensuring divers are well-informed when planning dives that require careful management of nitrogen absorption and release.

Other guides, while they may contain useful information, do not pertain specifically to the phase 3 validation process of decompression tables like the EDUG does, making it the key reference for this specific phase.
