I have another question about sub-neutral breathing. I understand that one of the major benefits of this type of breathing is the reduced exertion and ability to relax more and keep all tissues saturated. But, how do you take your final breath? I would think that a final big breath would do exactly what you've been avoiding throughout the breath-up. To avoid that do you take only a partial breath (say 3/4 max) and then pack the rest of the way, using only mouth and throat muscles and therefore exerting yourself less?

Also, when packing, how far do you pack? At what point does the effort to keep your breath become more detrimental than the benefits of having the extra air?
