There was a joke floating around in the IT community a few years ago... it would be boring here, but the punch line was a product marketing manager says "The great thing about standards is there are so many of them."

First there was fussing that no test results were published. Right now there is fussing that it's difficult to compare the testing results. I hope divers don't think that having uniform testing standards will be meaningful. If test results begin driving the purchasing decision, the manfacturers will start delivering units engineered to 'test well' in the lab, rather than 'perform well' in the real world. The manufacturer's simply start 'gaming the system' of independent testing.

And shame on whomever wrote the Jetsam pdf's for copying without permission or attribution, in their SK results document, an RMV/CO2/Work chart I researched, wrote and published on my website to document some test results for another brand of rebreather. (I recently edited to remove the reference to a Navy S.E.A.L. because of some specific issues.) By copying out of context, the Jetsam author has left the reader without an understanding of the underlying data that was used to produce the chart, and has deleted some important source references and mathematical assumptions.
