Chuck,
I believe that what you have proposed is indeed a valuable serviceto all of us. However, as I do not have any of the measuring tools that you mentioned in your post, I am not able to supply any data from my bikes. I would nonetheless be grateful if you or any other competent person with the proper tools were to take note of the measurements at le cirque. I believe many other willing contributors are in the same situation as me.
