How about where the style guidelines are historically inaccurate? Classic American Pilsner is the only beer that I attempt to brew to style. I probably have more experience with the style than most amateur brewers, especially brewing it with heirloom, period correct yeast strains. If brewed correctly, CAP resembles Bohemian Pilsener more than it does German Pils. The immigrant brewers in the Mid-Atlantic states that created this style were attempting to replicate Bohemian Pilsener (which is reflected in names such as National Bohemian). The surviving period-correct yeast strains are weakly attenuating, Saaz-type diploids that are anything but neutral and leave residual diacetyl because they are so flocculent (e.g., Christian Schmidt, August Schell, Leopold Schmidt). Brewing this style of beer with a Frohberg triploid lager strain should be considered to be a fault; however, the style guideline is written such that a clean fermenting Frohberg-type yeast strain should be used. Updating the CAP style guideline to make it more historically accurate is one of the reasons why I am attempting to join the club.
I think the style guideline authors have a difficult challenge balancing between modern interpretations of a style and historical versions. At some point I imagine it becomes necessary to split a sub category if the modern and historical drift to far from one another.
In the case of your CAP if it doesn't do well in the CAP sub category due to your adhering to a historical interpretation of the style then you might try 23A.
