At one time both of these nice reports were available from Leica USA. Yesterday, someone published the site where this could be downloaded but I did not copy it since I have the hardcopy in my file. The laboratory technician writes: "With the measurement method we use, sharpness values can be determined with absolute precision." If you have not read the report, I would commend it to you. It is very, very complimentary of the Leica lenses.
