The following rate of ascent for diving is acceptable when using the USN/NAUI dive tables?

Explanation:
Being able to ascent safely hinges on giving dissolved inert gas time to off-gas from your tissues. The USN/NAUI dive tables use a rate of ascent that tops out around 30 feet per minute, which provides a good balance between a reasonable ascent time and a safety margin against decompression sickness. Climbing at this rate helps ensure you stay within the no-decompression limits and reduces the chance of bubble formation as you rise. Going faster, like 40 feet per minute, increases the risk because gas may not have time to off-gas properly. Slower rates, such as 10 or 20 feet per minute, are safer but are more conservative than the standard maximum the tables assume. So, 30 feet per minute is the acceptable rate.
