While that's kind of what I meant by minor issues, I see from your statement
that they might not be so minor.  My ability to compare is limited to one
NAUI course, one PADI course and one SSI course.  I took the first and sat
in on the other two.  I did not notice significant differences in
presentations of diving related material, but do not claim that differences
were not there.  I was understandably focused on the material rather than
the method.  I bow to your better knowledge of the instructor side of the
issue.
