b1gcountry,
You sound like you are doing really well, but should have initiated lost diver protocol, meaning looking for one minute while keeping the 4 divers together and then waiting at the surface for your instructor if not re-united? This could have been a teachable moment for the other 4 divers as well. Think worst case scenario. It did work out, but I wonder if your instructor advised you the same.
