Aaron, if you still have further questions after the answers above, PM me.
As for the PT standards, the little bit about it being interim has been there for a very long time. It has been interim since at least 1999, when I did my first course, and probably even longer. That said, I participated in the evaluations for the new Diver's PT Test, and I am glad that they are finally near completion. I suspect that I may have done my last annual Divers EXPRES test, and will now be able to get exempt without worrying whether or not my inability to crush stones with my less-than-super-grip will cause me grief. The new test consists of a lot practical activities that bear a striking resemblance to what we as divers do.
It is broken into 3 sections:
land based - lift tanks, move kit, walk up and down ladders with tanks on, pull on ropes with great weights attached
Pool based - tread water at neutral buoyancy with a 5 lb bean bag in your hands, swim several lengths dragging a load,
Pool based - underwater - complete a timed distance swim at about 4FSW (works out to 8 x 90 second laps)
Its not too hard, but you sure know you are doing a test. It is way better than the CF EXPRES test, which you will still have to do anyways, but only to CF standards req for your age.
