I wonder if one could use the Statcast data pool (especially as it grows larger) to extrapolate data on outcomes in games played before the pompously named "Statcast Era". For the sake of argument: if, say, right handed hitters have hit eight hundred home runs a distance of 440 feet to left center field since 2008, and we have all the data on exit velocity and launch angle, could we then take that data and assign a likely value for exit velocity and launch angle to a 440 foot home run hit by a right handed hitter in the 1982 season? Prognosticating backwards is silly, I admit. Just a passing thought
