BB G3 Final: Louisiana 14, Troy 13

What is “average ERA”?

Did you add them up and divide by the number of pitchers?

I just did it that way for the 2013 numbers (because it was the fewest and fastest) and that’s what he did.

Sorry sir, but that’s not how ERA works.

Take the top 10 or so guys in innings pitched on each team. Add up all of the innings those guys have thrown (And fyi, when adding 20 and 20.1 it’s actually 20 and 20.33333, and 20.2 would be 20.66666). Save this total innings number.

Then add up the earned runs those same guys have allowed…and multiply that number by 9. Then divide that number by the total innings number to get the combined ERA of those 10 pitchers.

[sportsfanatic21]

Yeah, I just added them up and divided by the total. Not considering innings pitched or any other metric they may use to calculate average.

Is the average normally a weighted average based on innings pitched?

Yes. There’s no such thing as an average earned run average. Only an earned run average

[sportsfanatic21]

I just ran the top 10 in innings pitched for this years team and the combined ERA is 3.85

I’d be interested to see how that stacks up against the other seasons, but don’t have time to do that right now.

has to be weighted by innings, not pitchers

yea, averaging ERA gives #10 the same weight as #1 and skews the number

2013 combined ERA of the top 10 in innings was 4.39

I’ll do 2014-2016 later on this afternoon.

that is not accurate either unless you weight each pitcher by innings pitched

I updated based off of your calculations and the updated team RPI for the top 10 each year are as follows:

2024: 4.3649
2013: 4.6898
2014: 3.3963
2015: 3.7871
2016: 3.6577

I tried adding the xlsx in the event I still didn't calculate it correctly. I just grab the numbers from ragincajuns.com though.

This years top 10 in innings are at 3.85 and 2013 at 4.39, so I’m not sure how you’re getting what you’re getting

I did like suggested above (sum of IP (adjusted)) divided by (Runs allowed * 9)

Are you computing RA or ERA? Your "Allowed" column is using runs ... not earned runs.
