Explain why the RDP surface interval credit table is significantly shorter than that of the US Navy tables and why such a difference is possible.
The DSAT RDP surface interval credit table takes a shorter amount of time to off-gas excess nitrogen when compared to the USN tables. This is due to the fact that the RDP is based on a 60-minute controlling washout halftime, while the USN table is based on 120 minutes. The RDP basically gives you twice as much credit for surface intervals (although that statement is not exactly mathematically accurate). As a side note, the RDP and the US Navy table are the most common tables taught during beginner scuba lessons.
The RDP was designed specifically for no-stop (no-decompression) diving while the USN table was designed for decompression diving. By limiting extended exposures and decompression requirements, the RDP is better suited for multiple repetitive dives in a single diving day. The USN table was designed for navy divers doing one or two missions potentially requiring decompression.
