>There is no simple formula to compute what constitutes a minor, significant or substantial peripheral inert gas load. The actual conditions vary as a function of the individual, thermal protection, physical activity and dive profile. Accepting the difficulty of computation, I encourage a simple rule of thumb - delayed gratification. Enjoy the thought of the hot tub or shower for a while instead of jumping in immediately. The period of delay will likely be driven by human nature. Those unwilling to wait will likely jump in regardless. These would be the best candidates to practice more conservative dive profiles. Those with more restraint may delay five to 30 minutes with slightly less concern over the dive profiles. Another compromise would be to employ a lower hot tub/show temperature. Much comes down to the thoughtfulness of the diver. Decompression safety, as with many things, is a matter of balancing strings of decisions so the net outcome is in your favor. My approach is to stack as many factors as feasible in my favor to compensate for the Murphy effect or chance that we see frequently in decompression sickness.
