You and I do both have the additional problem that we teach to a standard that greatly exceeds that of the recreational community so we are faced with the question of when we should, or should not, apply that more stringent standard, the commercial one for you and the scientific one for me. That is one of the reasons that I do not teach "recreational" diving per se, but consider all training that I do to be under the scientific diving standards.
Yes, it's a perspective that finds us in an interesting situation, isn't it? I appreciate your outlook more than I did before, as I was unaware (until recently) of your position. Thanks.
