How Important is Home Field Advantage in the World Series?

That is the name of an article I wrote a few years ago for Beyond the Boxscore. It is at How Important is Home Field Advantage in the World Series?. I figured out the probability of the team with HFA winning in 4, 5, 6 and 7 games and then added those together to get 51.52%. Not everyone agreed with my methods and you can read about that in the comments. I got reminded of this because Sky Andrecheck recently wrote an interesting article at Baseball Analysts called Is The All-Star Game The Biggest Remaining Game for Dodgers?. He came up with 51.26%. We both used the historical average of home teams winning 54% of the time in regular season games.
