Minimum loop

Why?
Because you are on constant depth the amount of diluent will not change so if you have one breath and a bit over and you breath down the oxygen to one breath exactly then you know that you need to add a littel oxygen to the loop. That way you can fly the breather without "knowing" you pO2...

Pierre,

I apologize for being brief. Seriously, I was not intending to flame you nor your instructor. It was just an irritation on my part that we don't have a set standards so all instructors from all different agencies could cover everything necessary.

The other excuse is I am little stress at work lately as well

It is just that when I do a course, my intention is to transfer everything I know to the students. If it is something they can't use right away, at least they are exposed to them, get a chance to practice them in "controlled environment" so they could go on doing more practice on their own later.

I think everyone already gave you the run-down on MLV, so the only thing I think I could add is given you this scenario of MLV application as a mental exercise...

You are in a silt-out in a cave.
Your set-point is OK just before the silt-out.
You can't see the display on the PO2 meters.
You have the cave line in your hand and know which direction to the exit.
The depths to the exit is constant (just to make the example easy).

If you are using MLV, you should be able to exit with relatively good confident about your PO2 without being able to see the PO2 displays.

How ?
