Greetings!
On a similar note, I've noticed that each of the "contemporary" mauufacturers has a "slightly" different way of explaining the "measuring process".

It seems to me that, besides the diffences in wording, individuals (even newbies) will have their own ideas, and make their own "slight" errors in measuring. *I* did!

I've also noticed that people tend to like "what they have", and stick with it. (As in, "My current kilt fits like "this", and I like my kilt...So I'll order my "next" kilt to fit the same way...") So, some of the trends..Intentional or not..May become "self-propagating, so to speak.

Just my opinion, of course!
