Park Factor mythology

I ran a weighted average from 2003-current on home run differential home vs. away (aka Park Factor), here were the results:

To prevent confusion in the corporate name BS, I'll list it by team:
1 Arizona Diamondbacks 1.35
2 Houston Astros 1.29
3 Chicago White Sox 1.28
4 Texas Rangers 1.22
6 Chicago Cubs 1.21
7 Cincinatti Reds 1.13
8 Toronto Blue Jays 1.13
9 Colorado Rockies 1.12
10 Milwaukee Brewers 1.08

Yes, Coors barely makes the top 10. Apparently the humidor they keep the balls in has made a huge difference. I will note that Coors has the highest RUN differential of any park, but specifically homeruns are not quite as common as you think.

Other surprises were San Diego's PetCo falling right in the middle of the pack from a Home Run factor, as well as Anaheim being a relatively homer-free park.

It was a 10 minute Access/Excel analysis this morning while I was waiting for my tea!

What Park Factor mythology does this disspell?

The big issue with Coors Field (and MIle High before it) has never been solely home runs, but also doubles and triples (which tie into overall park factor and are individual categories themselves).

Most parks that give up a lot of home runs retard triples (and vice versa - SBC/Comerica), or they're about average for doubles, etc. - size balances out the three factors. In Coors they're all up fairly high, including home runs.

2005:
Runs: 1
Doubles: 4 (Fenway's green monster numero uno)
Triples: 4
HR: 8

2004:
Runs: 1
Doubles: 2
Triples: 4
HR: 4
