The illustration that was first submitted for their consideration, was adjusted by the Technical Committee before it was accepted for addition into NFPA 13. The original submission showed a 9 ft wide by 2 ft deep entry vestibule on both sides of the corridor. I believe that when the figure was revised the "2 ft 0 in. max." should have been edited out.

There appears to be an extraneous bit at the bottom that says '2 ft 0in. max' It looks like this is a holdover from a modification made to figure 6.4.6.3.3.2 in the 2013 edition of NFPA 13R. I'm wondering if the bottom of the figure accidentally got chopped off in the 13 version of the figure, and that the shadow areas behind the sidewalls in a hallway are allowed in a 13 system as well as a 13R system. I checked the 2016 first and second draft reports but didn't see any comments or proposals regarding this, though. Is this just wishful thinking on my part, or did someone goof up when they put the figure in? Any thoughts?
