Usefulness of term
The term was used more often in the early and mid-2000s, when college and high school tournaments were more likely to imitate CBI or bad local formats. Since every full-length tournament in collegiate quizbowl besides actual NAQT events uses untimed tossup/bonus format, and most use questions that are closer to ACF style than NAQT's, it is unclear what helpful information is communicated by dubbing a collegiate tournament mACF as opposed to not doing so. It is generally more effective to give a more detailed description of the intended length and difficulty standards of one's tournament (e.g. "7-line tossups, difficulty akin to ACF Regionals 2010"), and more tournament announcements have done so since the early 2010s, leaving the term "mACF" behind.
