I suppose so- haha I would examine strangers, but I might get in a little trouble if they spot me staring at their butt! lol!
I guess I was just trying to say everyone's actual length at classic would be different. If you measured a group of people who all had 'classic' length hair they would most probably be all different. It's not so a much a single length (i.e. at a certain increment in inches) but continuous - if that makes any sense?
