New Ballpark, Better Record?

Since the Cardinals are moving into the new Busch this 2006 season, I was wondering what effect a new ballpark can have on a team. I looked at teams who had moved into new stadiums in their same city since 1992, the start of the "pretty ballpark" generation. I have listed the new stadium and year of its first season. I then have the record of the last year in the old home and the first year in the new dwelling.
Camden Yards, Baltimore, 1992
- 1991: 67-95
- 1992: 89-73
Ameriquest Field, Texas, 1994
- 1993: 86-76
- 1994: 52-62
Jacobs Field, Cleveland, 1994
- 1993: 76-86
- 1994: 66-47
Coors Field, Colorado, 1995
- 1994: 53-64
- 1995: 77-67
Turner Field, Atlanta, 1997
- 1996: 96-66
- 1997: 101-61
Safeco Field, Seattle, July 15, 1999-2000
- 1999: 79-83
- 2000: 91-71
Comerica Park, Detroit, 2000
- 1999: 69-92
- 2000: 79-83
AT&T Park, San Francisco, 2000
- 1999: 86-76
- 2000: 97-65
Minute Maid Park, Houston, 2000
- 1999: 97-65
- 2000: 72-90
Miller Park, Milwaukee, 2001
- 2000: 73-89
- 2001: 68-94
PNC Park, Pittsburgh, 2001
- 2000: 69-93
- 2001: 62-100
Great American Ballpark, Cincinnatti, 2003
- 2002: 78-84
- 2003: 69-93
Citizens Bank, Philadelphia, 2004
- 2003: 86-76
- 2004: 86-76
Petco Park, San Diego, 2004
- 2003: 64-98
- 2004: 87-75

So, basically, if a team's owners build you a band-box stadium, you are doomed. Teams like Houston, Cincinnatti, and Texas fared worse after moving into their new stadiums.
San Diego, Seattle, and San Francisco all had much better seasons. Their stadiums skew towards pitchers.
Overall, 9 of the 14 teams to build new ballparks had better or the same records after moving. 7 of those nine won, or were on pace to win, ten more games than the previous year. That is pretty remarkable.
Of course, there are other factors that go into a team being better from one year to the next. In some cases, maybe the owners of a franchise decide to spend a little more on their payroll as a thank you to their fan-base for paying for the new stadium. I decided to just look at the new stadium as a difference from one year to the next.

No one knows exactly how the new Busch is going to play, but it doesn't seem like it will be a band-box. As far as the Cardinals are concerned, I see them having an equal or better record because of the new stadium.
