The lights thing is a myth. HFA alternated between West and East back then. I wanna say 85 was the first year they switched to best record. Not true. '84 was the East's year for HFA, but they didn't let the Cubs have it because they couldn't have any night games. '89 was still alternating, and that year was the West's turn (The Cubs finished 93-69, while the Giants finished 92-70, but the Giants got HFA). Wrong on both accounts. '82's NLCS went 2 in St. Louis, then 1 in Atlanta(setup was 2-3). '83's went 2 in LA, then 2 in Philly(again 2-3). '89 went 2 in Chicago, 3 in San Francisco(set up was 2-3-2) I can't really figure out how HFA was determine after '84 as the West had it in '85 and '86, both years with inferior overall records. Head to head maybe?
