to a few questions raised,
The establishment thru which I received the certification seems to be running the OW course on a set schedule. Theory on Saturday, pool "training" the following Wednesday, OW dives on Sat & Sun. The next class begins the following Saturday. So, yes, you could deem this as a sort of "mill". Many would say they are more interesting in the turnover than in their dedication to the dive community. $$$$$$$$
Secondly, the drills which I identified we did not complete were specifically identified in the current "Go Dive" OW book from PADI. As I had read the book twice (once before beginning the classes, the second between the theory and OW dives), I was well aware that we did not do some of the drills. When the question came up as to what drills were missed, I went back to the manual and listed them directly.
I agree that some of the drills can be combined, and performed without a student's realizing that they are being done. However, to completely remove your BC and/or weight belt (if not integrated) while sitting in at least 8' of water is pretty hard not to miss.
I agree with the reply that when you are diving with a previously unknown buddy, you expect that person to have completed all the required skills. Anything less lends you to unknown risks. Personally, I feel I have completed those missed drills. I've done them several times in my own pool, and feel quite confident to be able to: first, not panic and be level-headed enough to remember them, and second, to be able to actually perform them if the need arises (or my dive buddy).
Granted, those who took the class with me could be in some serious situations if they got tangled up in a fish net, discarded tow rope, etc. And, unfortunately in one respect, our area of Florida has warm clear water and a lot to see in less than 30'. This in itself tends to make one drop their "guard".
I'm still pondering the situation. I'm thinking of having a real heart-to-heart with the instructor. Maybe that would be all that is needed to get his students the required training. We'll see......
