I don't know if it was well reported, but in the media gathering Harris had to discuss the new dimensions, he had some lines that really impressed me.
He reminded the media that park effects are prone to randomness and take a while to stabilize. Somebody asked about a three year window if that was appropriate, to which Harris said usually not that long, depends on the amount of balls in play.
He also said they now have access to weather data to help parse data and evaluate the park factors. I have to think that data is being used to evaluate players and parse stat lines too.
Music to my ears.
