~ Dedicated to my friend Joe, whose passion for this subject also goes back more than 25 years.



PFOPP is a merging of Park Factors, game by game, where the pitcher started + the relative run-scoring ability of the OPPosing teams, game by game.
> 1.000 is beneficial to the pitcher's adjusted ERA.

OPPWL is the composite W-L record of the pitchers' opponents, in all of the games the opposing pitchers started that year.
> .500 is beneficial to the pitcher's adjusted W%.

RS is the average Run Support the pitcher got in the games he started, divided by the average run support in all games by his team.
> 1.00 is beneficial to the pitcher's ability to win games (thereby reducing his adjusted W%).

* The 2020 season is considered a 'full' season by MLB in the sense that it was as full as it could be. However, it was about 44% shorter than the next shortest season that IS treated as 'full' in this study (1981), not nearly enough data to be indicative of a full season. Therefore, for this season, StDev scores were adjusted by 44%, plus or minus.
