it isn't ideal but it could be worse. The best beers win, usually. Alternately, I think it is wrong for beers to win a first round ribbon, for the brewer to be asked to send 3 more bottles at their own expense, and THEN for the beer to be kicked out as out of style. Which is exactly what happened with a Fruit Beer this year. That person deserved the gold and if it had been my beer that got screwed I'd be pretty pissed. Oh, and mini-BOS included a couple coconut beers (21A) and a Belgian (16E).
If it were out of style then it got lucky to win the first round, not screwed to loose the second. Plus first round beers can be all over the place, maybe it was out of style but still the best example. Then progress to the second round where it is judged against other winners and being out of style is more of a flaw relative to the other entries.
