I entered my 1st comp. 3 years ago and won. It was a local, non-BJCP event but I won a brew-with-a pro day. I submitted the same beer to a BJCP event later and it got a respectable score, but did not place in it's flight. The following year I won the local event again and brewed with a different brewery. That year I caught the bug and entered several BJCP comps. with different beers and did pretty well- a few 2nds, thirds, and 1 1st. This year I got a 2nd in the local event, but have entered about 8 different BJCP comps and Nationals. Mostly because I want to get feedback on my beers. The ribbons and swag are nice too. Mostly I enter different beers in each competition, but have submitted the same beer to a few. The scores were not necessarily close, but the comments are always helpful.
