Can repetitive group designations be transferred between the RDP and US Navy tables?

The assertion that repetitive group designations cannot be transferred between the RDP (Recreational Dive Planner) and US Navy tables is rooted in the differences in the decompression models and algorithms used by both systems. Each system generates its own specific pressure group and repetitiveness considerations based on distinct variables, such as dive depth, time, and the different assumptions about allowable nitrogen uptake and off-gassing.

As a result, using the RDP's repetitive group assignments alongside the US Navy tables may lead to inaccurate decompression planning and increased risk of decompression sickness. It's essential for divers to remain within the guidelines of one decompression model to ensure safety and maximize efficiency, especially when planning repetitive dives. By sticking with one system, divers can have confidence that their chosen methodology correlates directly with their dive profiles.
