So size of anticontexts may not be as significant as numbers of anticontexts and numbers of contexts.

Except, in a high school, jock isn't one context and burnout another, but rather jock vs. burnout is the context. A college musical context might be rock vs. dance vs. pop vs. indie (not to mention subcontexts and suboppositions, and maybe country is in there somewhere), except "versus" to some degree will be "and" (and vice versa)(and vice versus).
