I see the numbers, but I do not understand them. Is someone suggesting that we know how thick the matzah of R' Chayyim Volzhiner was? Or that of the Chofetz Chaim? To any degree of accuracy at all?

Especially given the fact that a single handmade matza can easily be of non-uniform thickness, how can anyone presume to know that a given matzah was closer to 1.5 mm or to 2.0 mm? And especially without putting a ruler to it!!!

(PS: The reference to "some years ago on the list" might be referring to the post at http://www.aishdas.org/avodah/vol04/v04n019.shtml#05  But if so, it offers even less data than this post does.)
