I'm curious how many of those are throwing errors versus fielding errors. One of, if not my last competitive game ever as a pitcher (in our local little league), I struck out the side in the first. Drove in a run B1 with a SAC fly to give us a 1-0 lead (and I was not a good hitter...). Top 2, man on first (maybe one on second as well), a good friend of mine lays down a bunt. Don't recall how many outs there were, but I threw it down the first base line for an error. The flood gates opened after that. Not sure I lasted through the inning. A simple throw, not made. Was a big game too. Top two teams in the league, late in the season. The coach called my house to tell me he wanted me pitching in that game. Didn't get the job done.Pitchers play defense too... some of them play it poorly. Honestly, my observation is very few play defense really well. In 2021, our pitchers accounted for 14 of the team's 72 errors (19%). 3B was the only position accounting for more errors (18) on the season. Pitchers who can't field their position fall in same category for me as basketball players that cannot make free throws. Put in the work... get better at it. The dividend is only going to help you and the team succeed. Maybe those issues (when they arise) are on the coaches. I don't know.
There is some irony (statistically speaking) that a pitcher's error(s) have a positive impact on their own (or the pitcher they just relieved) ERA.
Scenario... 2 outs and Pitcher A walks the bases loaded. Pitcher B is brought in to shut the door. Ground ball to 1B... 1B tosses to pitcher covering and he fumbles it (E1). Safe at 1st. 2 runs score. No earned runs charged to either pitcher A or B no matter how many are scored in the inning. (I think I'm right about that)

@GTNavyNuke ...I doubt any of the above relates at all to your question or your analysis.
And yes, you are correct about that ERA wise. Even if it's pitcher A that bobbles the ball for an E1!
