Judges in competition do not have access to your receipe sheet during the judging of the competition. The only information they have about your beer is the style that it is entered in and a copy of the BJCP guidelines for that style. They will get information regarding "speciality" ingredients if it is in a category where that is indicated, ie 16E, 23, etc. What matters most from a competition perspective is how the beer tastes, not what is in it. If it tastes like an APA, enter it as an APA irrespective of whether you used Munich, or even if you used non-american hops.
