Sorry about the confusion on that! Has anyone gone from hyperventilating (5-6 quick breaths only, not anything super intense) to the full exhale right before your final breath? I'm interested to see if you've found any differences in the water
IMO, moderate hyperventilation(as you described it) as a 'booster' is not very effective; assuming that by 'quick' you mean rapid, relatively shallow breaths, you're actually just moving around air in the upper area of your lungs, while the lower part stays filled with dead air for several seconds. For longer dives, I use a combination of HV(more intense and deeper than what you seem to describe), and that final deep exhale/inhale. Definitely results in longer bottom time for me.
