I just read this again, and it brought back memories of another learning situation for me. I was in a class, diving as part of a team of three. We were on a site I didn't know, but one of the other divers did. He described it and told us what he thought the best course was to see it. He was not going to lead the dive, though. We made a plan, and got in the water, to discover some very strong current making it VERY difficult to execute the dive as planned. Rather than change the plan on the fly, we kept trying to execute it. I was on the bottom, trying to pull and glide against the current, because I couldn't even kick against it very well. This probably went on for ten minutes, while the leader tried to follow the plan, which had proven to be faulty, and the two of us tried to follow the leader, because she was leading. Dumb! Eventually, we veered off and found the edge of the wall, and discovered the current was far less at depth.
The lesson I learned from this is that "Plan your dive and dive your plan" is a great mantra, but "Plan your dive with some contingency plans, and be prepared to adapt when water conditions don't permit executing the original plan, AND have a way to discuss this (we carry wet notes for just this kind of reason)" is much smarter.
