I appreciate your experimental method. Often, people answer questions on forums with the "guess and surmise" method or they just repeat misassumptions, leading readers astray. You on the other hand have actually explored the mechanics and use of this lens, and your information is factual and therefore indispensable.
I agree some of the other lenses should be explored, and written up in a scholarly manner for a useful database. I've seen more of this testing done with small format for some reason. You can find several lens tests for Leica Screw Mount, for example. I suppose one reason older lenses are harder to test, is the manufacturing variances in the 19th century, and the lack of documentation (and fewer lenses and users).
