You might add a reminder to exhale all the way to the surface, should the user find themselves in an uncontrolled ascent
My dive master told us some pretty horrible stories about not exhaling on the way up to drill it into us to keep breathing regularly. One was about a guy who was cleaning a diving pool, 18 feet deep, with a scuba tank. He was taking a break and took off his tank and took a breath off it, held it and shot for the surface. He was lucky. He ended up coughing up some blood but no major damage.
Of course, this is the same dive master who told me about skip breathing as a way to get more bottom time off my tank, which can make a dive go really wrong really fast. Steady breathing is the way to go, short dive or not.
