Hey guys... thanks for the very detailed feedback and good suggestions... I agree with JDS' recommendation... I probably won't wait around for fills anymore... but noteworthy...$7.50/hr is a high paying technical salary here!

How do you "cascade" if the supply bottles are not interconnected?
Correct... it's not a cascade but rather a series of individual cyliders arranged in an attempt to maximize the available O2 in the bottles.
Lastly, I guess I'm most surprised by the fact this is more of common experience than not... the poll really seems to suggest that rapid O2 fills (despite all the risks) may be a fairly common mistake.
