Therein lies the conundrum of risk/reward. Possible impact: relationship burned with LDS and/or instructor and multiple LDS in the region as I get a rep of a troublesome student considering it's a long time, well known shop. Return: a poor experience is changed positively for unknown amount of others - which has value, without a doubt.
Apply likelihood to impact to determine risk and number of students+likelihood of change+degree of improvement to determine reward. Too many unknown variables.
Overall, what would a maximum value AOW, given current curriculum, provide an OW diver?
1. Rated to dive deeper (but the bottom of the dive site is 61')
2. Another navigation dive (navigation is taught in OW by orgs other than PADI) - so practice
3. Peak Performance Buoyancy (which can be done by reading about proper weighting techniques and practicing) - net value is practice with a little coaching - 30 min or so.
4. Drift - not available in my area
5. Night - no huge difference over a night dive with a DM in the water (IMO)
6. S&R - introduction to basic search patterns used on land in the water - there could be value here in practice.
7. Fish ID - really?
8. nitrox- no substitute for the real course, and the value of nitrox is obvious
9. Wreck - not available in my area.
In my view the value of AOW is deep dive and practicing your skills. So rather than tell the shop, I simply stick "scubaboard.com" notices on their bulletin board so they get certified, come here and learn the skills they can then practice on their own and guide their own development.
Based on my reading here and review of online course standards, I'd say GUE fundamentals > AOW, and passing THAT should be accepted as such. It'd be easy to throw in some deep dives on a weekend with a deeper study curriculum and get OW+AOW all done at once. That'd make it cheaper to get people into the sport, which would be better for everyone.
I'm just glad I was old enough to see that my instructor was not someone I should be learning from, but instead serves as an example.
