Now, you realize that your reference had BOB listed as a more hitter friendly park than Minute Maid in 2003 (13 vs 15) and 2002 (6 vs 12), right?

The text written on the parks is based on data up to the '01 season

That said I don't put too much into park factors until it becomes an exaggerated case (Coor's Field vs. Dodger Stadium). They vary year by year and are heavily influenced by the quality of the most recent pitching staff. For example, I'd expect BOB to appear as a more exaggerated hitter's park because of the low quality pitching they had most of the year (however the terrible bats did their best to keep things low)
