I tend to think that when the list is longer than the rest of the article, there's a problem.  Either the history and characteristics should be expanded, of the list should be culled.  I personally like the consensus that was reached in the Tripel article between  and others...myself included.  We decided that the country of origin should be highlighted with the most examples.  There we did Trappist, Abbey, and Foreign.  Foreign includes all non-Belgium examples.  This way the article is an article in an encyclopedia, not a list.  People can find lists anywhere, and the article should reference this.  Also, the style statistics are bad.  When you say style statistics, it sounds like a prescription, not a description.  An encyclopedia should follow the latter, and if the former is used, a citation should follow...And you'll not find a valid one for this style in it's country of origin.
