Yomgui, I have not read this thread completely, but I did download the thesis you referenced. The tests you're talking about (the thesis) were done on a Master Airscrew propeller. Our prop measurements showed that these propellers generally are not that great good (low efficiency relative to many other brands that we tested). I think the real test of something novel like this (saw notches) needs to start with a baseline that is already very good. Then the challenge is -- can it be improved? I think your own tests w/ an already good prop show that saw-notching the leading edge does not help. FWIW - We will not be trying these same tests because I think we'd come to the same conclusion.
