So, all these charts, graphs, articles, opinions are very interesting, but in practice, none of them are conclusive and probably never will be.

Not quite true. Plotting two charts with and without stabilization is a legit way to measure the stabilizer efficiency. In such way you compare your own hands with same hands, improved by stabilizer. Depending on your skill, both graphs will be affected, but difference between them is that matters.

CIPA test protocol probably utilizes more or less the same technique, the difference is that the "hands" are mechanical.

That is the problem with your testing procedure, all hands are not identical in the shake they have. Even the same hands vary in the way they shake on every shot. That is a huge variable in any hand held test. Doing a hand held test for stabalization will never give you the same results more than one time.
