Why can't I dive twice on the same tank?

It might help if you found some off time to walk the objecting party through the math and show them that it is the cuft that matters more than the psi, then again it might have the opposite effect.

That's what my rant is about:
1) I have to pay for a full fill even if I don't use a full tank.
2) I would rather have 1 less tank to schlep.
3) I can do it safely
4) I understand the physics, even if some don't

If the rules seem to silly to deal with, I look elsewhere.

I have no problem dealing with that I believe in always respecting the DMIC & the Boat Captain regardless of your level of training/specialty .

Anyways, thanks all for listening to my rant.
