Mark,
Agreed.
In this case, the testing was independent, so the methodology was in conformance with CE standards. The testing organization writes their own protocols--which is what makes the test results so significant.
We also know these are paramaters that on one could really dive to so your point is well made.
Hopefully if and when other Rebreather manufacturers release their testing data, it will be to the same standards so we will have a good baseline of comparison --essentially comparing all apples as has been mentioned. I suspect that's the reason the testing data is not as 'real world."
I am impressed with KISS that they undertook to have their units tested and they released the data.

Don't get me wrong I am both grateful and pleased that these tests were carried out and Jetsum/Kim should be applauded for doing them.
At least the base lines are comparable with other known units. Id like to see the test data for a Meg and rEvo beside this and the Inspo & Boris data.
My comments are aimed at the value of the test dater on ALL units. When i dived an Inspo we all knew the Three hour and staggered depth rules but most of the divers doing my kind of diving were happy to push 5-6hours on the scrubber with one big dive or multiple shallow ones.
There were enough people doing it to form a sort of acceptable limit for the scrubber.
Now I am on a KISS I don't have the benefit of the same level of empirical data but we kind of accept the scrubber is a similar (slightly more in fact) load of Sofnalime so we can expect similar results.
But lets face it, were just guessing.

EDIT: I should point out I hardly ever go over three hours on a scrubber but on a red sea liveaboard id probably do 4 60ish min dives down to 25-30m with a third the dive in the shallows
On big dives I am obviously doing most of the time at 6m
