That seems like an uncharitable read. The phrase "an obligation of result, not of means" simply stating that the regulation doesn't choose a specific methodology, as it only prescribes a standard for its results. It's as if regulations for clinical thermometers require accuracy within a 0.1C margin of error, but manufacturers can choose how the device works, and how to make it.

Of course, the scary part is that they would consider an 10% error rate to be OK.
