In my opinion there's 3 reasons to enter comps. #1 is to help the club that is running it. It's a fund raiser after all. #2 is to win medals #3 is to get feedback.
If you want feedback, enter your beer in the style you wish to master.
If you want to win, send your very best beer, and enter it in the style that it seems to best fit as you are drinking it with guidelines in front of you. As you are doing that, ignore the numerical data that you know and that's at the bottom of the guidelines. Go by the verbal descriptions and what you are tasting. (Aroma, Appearance, Flavor, Mouthfeel, Overall). The judges won't have your numerical data, so it's not like they have lab equipment to determine that your beer is .3% too high ABV.
