As it is, it seems that every manufacturer defines it’s marketing bucket differently… I know for a fact that not every semi QH saddle is the same width nor has the same bar angle![/QUOTE]
Ain’t it the truth?!?!?!?!?! 
Fitting a saddle to horse and rider is often a challenge because there are no identifiable national standards. So “QH Bars” to Circle Y does not, necessarily, mean the same as it might to Steele or Big Horn.
Even “16 inch seat” can mean different things to different makers (nevermind the difference between “English 16” seat" and “Western 16” seat."
This does not mean we abandon all attempts at categorization, only that we realize that some attempts at creation of a category are driven more by a Mad Ave. “create/fill a need” reasoning than any sort of functional, conformational, or historical reasoning.
