well,
2017 Home vs. Away OPS;
MLB league-wide, Home: .769; Away: .732
Astros: Home: .812; Away: .834
2018
League-wide, Home: .738; Away: .718
Astros: Home: .730; Away: .777
2019
League-wide: Home: .767; Away: .749
Astros: Home: .878; Away: .819
And, finally, Jose Altuve was .979 at home in 2019; .836 away.
Either it's statistically insignificant/random data, OR, there was a learning effect where it took the Astros awhile to get everything ironed out - in other words, while it did provide an advantage, it took awhile to develop the skill. Similar to learning how to count cards in blackjack.
