It's hard to tease out what 'raw reaction time' even is, because reaction speed is so context-dependent. I'm going to crib from the wonderful book Bounce by Matt Syed (as far as I remember).
Set up is that Syed is a former Olympian ping pong (table tennis) player whose day job is as a journalist for the BBC. As part of a publicity stunt for Wimbledon or some other tennis tournament, they had a "journalists vs pro tennis players" series of matches. Syed was paired with Michael Stitch of Germany. He said going in that he didn't think he'd be able to return an pro serve (~135mph), but would at least make contact with the ball.
Yet when the time came:
I saw the ball go up, I saw his racket make contact, and I heard it hit the curtain behind me.
Syed follows up with this:
My colleagues at the BBC may have just thought "oh well I just don't have the reflexes of a top athlete". But I do have those reflexes. The amount of time to you have to return a smash-kill in table tennis is 100ms, which is half the time it takes for a 135mph serve to reach you in tennis. I'm twice as fast as I should have needed to be.
He continues with the fact that a pro tennis player only "sees" the ball (and by extension an Olympic-level ping pong player) because of their expertise: they already have a pretty good idea of where it's going to be. But that expertise is domain-dependent (as Syed's anecdote demonstrates). I would imagine the same holds true for other amazing feats of perception, e.g. hitting a Major League fastball.
So your best bet, performance wise, is to become an expert at pinball. Play a lot. Get a machine with the glass removed, practice specific setups that you control by placing the ball. Get an intuitive feel for collision angles, etc. etc.
The quotes may be somewhat inexact, I don't have the book handy and am working from memory, but the gist should be correct.
