Ok first part, got it, good that you felt like you had a good experience in the class and you were comforted by the instructor and their advice on your shortcomings. I applaud your instructor for doing a thorough job, as it sounds.
However, by your own accord you have proven my point for me. You say: "I felt that I did learn to buddy better than I might have otherwise as it was the instructors eyes on me the whole time so I felt any mistakes would be noted and commented on."
Lets look at what you said, "I felt better bc the instructor was watching me" that is not going to be the case after the class, so who is going to look after you then? Did you check on the instructor to make sure he was doing everything correctly?(I know this may sound strange but again you should check on your buddy regardless of the experience gap.)
You say you were comforted by the instructor watching you, ok well I am going to go out on a limb and say your instructor will more than likely have more training and experience than your next diving buddy. So are you not going to feel as safe if the instructor is not there? Will you be able to keep yourself composed with your limited experience to assist your buddy (not the instructor in this case) if they were to have a problem or are you going to still be preoccupied with your own issues? Even more simply, will you be able to do the proper checks on your gear and your buddies gear before getting in the water, or will you feel like you will forget something that may be pertinent bc your instructor is not there?
Honestly, I really am not trying to start an argument by any means. I am not one of those self entitled, arrogant instructors that says anyone who disagrees with me can pound sand. I just hope you realize what I am saying in the examples above, if not no worries. I am happy that you are a new diver, the industry needs more and more divers to be trained properly like I feel you did from what you described. Keep diving the only way to get better!! I have been diving for 14 years, 27 years old now, and I still practice my buoyancy and other skills to keep them sharper than a razor, wish I could say the same about my IQ haha.
