Here's a rather strange thing I discovered while taking Extended Range is that if you are diving with a team, you tend to follow the team leader without realizing it. I was hovering at 120 feet (which was supposed to be the max depth of this dive) and my instructor was hovering facing me. I thought I was just waiting for an instruction from him, but he surreptitiously sank 5 feet - and so did I - without ever realizing it! I subconsciously breathed my way down at the same rate.
Later we did some excercises where we would hover and make fists. One person would be the leader responsible for the depth of the team. We would extend our arms and touch fist to fist and go up and down the water column by breathing following the thumbs up or thumbs down of the leader without losing contact. This is a fun thing to try with your buddy.
