Rule of thirds is for penetration, and may not be right even
then.

Rule of thirds in open water would probably be too conservative.
But 200 PSI left on a deco dive is cutting it way too close.
Clearly there wasn't enough gas to get an OOA buddy up, there
wasn't even enough to allow a little extra deco if it was
required.

You'll learn how to calculate this stuff in tech diver class.

And understand that getting bent goes with the territory in
technical diving. A reasonable proportion of techdivers of all
religions (TDI, GUE, etc.) have got bent. Some have done it by
not following procedures, some were following procedures and
still got bent).

A good starting class would be GUE Fundimentals. Even if you
don't drink the DIR kool-aid, there's lots of good stuff to
learn there, including how to use the redundancy of the doubles.
