Does Greg Rahn's "join order benchmark" reflect real world OLAP join scenarios?

Greg Rahn's "join order benchmark" has dozens of inner join queries on the IMDB database. Does this benchmark and the database itself reflect common real world OLAP join scenarios? How does a join optimizer's performance on these benchmark correlate to general join performance for the real world? For example: SELECT MIN(cn.name) AS movie_company, MIN(mi_idx.info) AS rating, MIN(t.title) AS complete_euro_dark_movie FROM complete_cast AS cc, comp_cast_type AS cct1, comp_cast_type AS cct2, company_name AS cn, company_type AS ct, info_type AS it1, info_type AS it2, keyword AS k, kind_type AS kt, movie_companies AS mc, movie_info AS mi, movie_info_idx AS mi_idx, movie_keyword AS mk, title AS t WHERE cct1.kind = 'crew' AND cct2.kind != 'complete+verified' AND cn.country_code != '[us]' AND it1.info = 'countries' AND it2.info = 'rating' AND k.keyword IN ('murder', 'murder-in-title', 'blood', 'violence') AND kt.kind IN ('movie', 'episode') AND mc.note NOT LIKE '%(USA)%' AND mc.note LIKE '%(200%)%' AND mi.info IN ('Sweden', 'Norway', 'Germany', 'Denmark', 'Swedish', 'Danish', 'Norwegian', 'German', 'USA', 'American') AND mi_idx.info 2000 AND kt.id = t.kind_id AND t.id = mi.movie_id AND t.id = mk.movie_id AND t.id = mi_idx.movie_id AND t.id = mc.movie_id AND t.id = cc.movie_id AND mk.movie_id = mi.movie_id AND mk.movie_id = mi_idx.movie_id AND mk.movie_id = mc.movie_id AND mk.movie_id = cc.movie_id AND mi.movie_id = mi_idx.movie_id AND mi.movie_id = mc.movie_id AND mi.movie_id = cc.movie_id AND mc.movie_id = mi_idx.movie_id AND mc.movie_id = cc.movie_id AND mi_idx.movie_id = cc.movie_id AND k.id = mk.keyword_id AND it1.id = mi.info_type_id AND it2.id = mi_idx.info_type_id AND ct.id = mc.company_type_id AND cn.id = mc.company_id AND cct1.id = cc.subject_id AND cct2.id = cc.status_id;
