Hi Greg,
I agree. I've always taken it for granted that Jasta 11 was Richtofen's Flying Circus, regardless of any add-ons. I also have assumed that, depending on the time period, that most all EA single seat scouts are percieved as Albatros or Fokkers and that all brightly colored A/C are believed to be part of the Richthofen's Flying Circus. I can even see where the germans might consider it a circus with the frequent moves from town to town by train and or air and the brightly colored aircraft involved.
Again, I don't see this term as a bad thing. Of course some use it affectionately and others use it while cursing, even still.
Best Wishes, Jay
P.S. Of course I am usually sorry for taking anything for granted and then there is that dreadful word "assume" ("Ass-U-Me")!
P.S.S. I agree with Dan-San, even if he meant to address Steven and not Stephen. I think(?).
