Precautionary Decompression Stop.
This is a stop at five meters (15 feet) for three minutes as a safety precaution when you have not exceeded the Maximum Dive Time. You should perform such a stop at the end of every dive. It is also known as a Safety Stop.
Deco for Divers - "Bubbling is controlled by the difference between the tissue tension and the ambient pressure - however off-gassing is controlled by the difference between the tissue tension and the inspired inert gas partial pressure. This difference, which is is known as the inert gas gradient, determines the amount of off-gassing. If this tissue compartment has a 5 minute half-time then the tissue will go 50% of the way from the current tissue tension to the inspired inert gas pressure in 5 mins."
Based on this wouldn't it be better served to recommend a 5 min safety stop for all no stop dives (1 min @ 6 meters and 4 min @ 3 meters) to get the fast compartments to reduce by 50%?
Why is the recommendation 3 mins, does it matter?
