Ascending well within no-stop limits signifies that divers can safely return to the surface without needing to make decompression stops. This is essential in recreational diving, where staying within the no-decompression limits ensures that dissolved nitrogen in the body can safely off-gas during the ascent.
When divers adhere to these limits, they minimize their risk of decompression sickness, a condition that can result from too rapid an ascent or failing to give the body adequate time to eliminate excess nitrogen absorbed during the dive. By maintaining a controlled ascent rate and remaining within the established limits, divers can safely exit the water after their dive without needing to pause for decompression.
While making a safety stop is a good practice to further reduce the risk of decompression sickness, it is not a requirement if a diver is well within the no-stop limits. The notion that all divers should surface together or that they must increase their descent rate is not applicable to the concept of ascending within these limits, as it focuses on the safety and management of the ascent itself.
