Historical Ballpark Modifiers

I am starting a project to make more correct era ballpark ratings. i like the idea of neutralized stats in historical play, but when you try to put them up against a ballpark, you come into a standstill. All parks have a 1.000 ratings for 2B and 3B, while home runs and average are all the same at each park, left and right.
The neuances of these parks don't come to life at all in a historical repay. Some you can hit for average but not home runs. some have no home runs but tons of double and triples.

So thanks to Seamheads great ballpark DB, I began to build my own park setup. Here is what i have created for 1977-79 as a starter (3 year chunks of time)
Lets take 4 parks.
Fenway, Dodger, Busch and Yankee Stadium as examples.
In OOTP you pull up these parks and you get 1.000 for 2b and 3b, while the average and hr totals for the parks are
Fenway 1.140, Dodger .968, Busch 978 and Yankee Stadium 964

Now here is these 4 parks brought more to life historically thanks to Seamheads and my "meaning" of their data to make it more OOTP friendly

FENWAY
AVGL 1.025
AVGR 1.045
2B 1.150
3B 1.015
HRL .975
HRR 1.045
It now becomes a right hand hitting haven as it should, though look at all those doubles to pick up now

DODGER
AVGL .985
AVGR .995
2B .880
3B .875
HRL .975
HRR 1.020
While slightly a pitchers park now in hits and home runs, look at those doouble and triples just sink into the dust.

BUSH
AVGL 1.010
AVGR 1.010
2B 1.040
3B 1.120
HRL .920
HRR .950
This sums up Bush in the 70's. Home runs are down, average is slightly up, but man look at those triples. Now get some guys who can hit with some gap power and speed, and voilla, there are the 20 triple season.

YANKEE
AVGL 1.000
AVGR .980
2B .975
3B 1.050
HRL 1.090
HRR .900
Now that is Yankee stadium we all know. Load up on your left hand power hitters and watch them hit the overhang, load up on right hand power hitters...and you will wonder what the hell you were doing.'

To me this starts to bring these parks to life,and as a GM, to start to make choices that more fit the ballpark. Jack Clark is really wanted in Boston, not wanted by the Yankees, while Gary Templeton as long as he can hit the gaps is a great hitter for the Cards.

Anyway, just a start, but wanted to share. I have all 26 parks for 1977-79 completed. Begining a new set of 3 years
