Breaking Pitches

Wouldn’t we need to look at the quality of the pitchers in both groups?  The cutoff seems to ensure we are at least only looking at starting pitchers.  I also don’t know that the “ratio” is what we want: I would rather have seen the before and after totals, instead.  The actual list of pitchers might have been interesting as well, as maybe some were clumped in the 70s, a time period when pitchers threw alot more than before or after.

We find that non-breaking ball pitchers throw, on average, 382% more pitches after turning 23 than before, while breaking ball pitchers throw 311% more.
