So... WHAT THE HELL WAS THE INSTRUCTOR'S TANK PRESSURE???

Remember years ago we had a long thread on what psi one should exit with when losing a buddy. These guys were close to the exit. No instructor worth their salt should have CONSIDERED exiting until their gas hit 1100 or so.

This guy probably EXITED with over 2000.

...####. Now I've started the guessing game! But my first thought when I read this was, why did the first person leave so early?

Not only should he not instruct, he shouldn't even cave dive. Assuming of course that my assumptions are correct.
So, if I understand correctly, the instructor should base his exit on time / gas, not on "I executed my search tasks without finding the students, so I need to call for reinforcements."?
