I don't think a setting making the ERG to ERA will work. If I understand ERG correctly, then ERG will be based on a 5 innings if the game only goes 5 innings. (In the case of a game shortened due to run rule or weather)

In NFHS (High School), ERA is still based on 7 innings, even if the game only goes 5.

I can scan this page of the rulebook and email if you want me to.

No, ERG is not based on the number of innings actually played, it is based on the number of scheduled innings. In the options for each game, there is an option for "Scheduled Innings". So for high school games, you would set that to 7, and ERG becomes a calculation exactly like ERA, but based on 7 innings. Shortened games or even extra inning games would still use 7 if that is the number of scheduled innings used.

For the "Showcase Games" that davidlimbaugh mentioned in his email, you would set Scheduled Innings to 9, and iScore would use 9 as the basis for ERA in those games. (If you still wanted to use 7, you would set scheduled innings to 7, but it sounds like they would actually want 9).

It is EXACTLY what is being requested, but is just not labeled "ERA", it is labeled "ERG".

Here is what we will do... in an upcoming release, we will add a setting where you can say you want your ERA calculation to match the ERG calculation. We still disagree until proven otherwise, but we really do try to make our customers requests top priorities, and this will give you a way to see what you want in the ERA column.

If you can not wait for that release (we will fit it in as soon as we can, but have higher priorities right now), we can think of two options. You can always export to any of the various formats we support, and rename the ERG column to ERA, and rename the ERA column to "REAL ERA" (just a friendly nudge... you can delete the column if you like). The second option we can offer is if you currently have a Team Website, or want to get a Team Website, we can configure your website to show ERA using the ERG calculation right now... if you want to go with that option, just let us know your customer ID and Team Name by email.

Thanks for being patient with me - just trying to help :-)

What happens with 'ERG' if you play games of 7 innings and 5 innings during the season? Example in high school is that if a tournament has rain, the games may be shortened to five innings to get them in. Over the course of a 30 game season, 25 games could have been 7-innings (even the ones that were shortened to 5 or 6 by run rule) but 5 of them could have been pre-determined 5-inning games. How is ERG calculated then? See what I mean?

You can decide how you want to handle it. Every game has a "Scheduled Innings" setting. If you want the 5 inning games to use 7 innings for the calculation, set the Scheduled Innings = 7. If you want the 5 inning games to use 5 innings for the calculation, set the Scheduled Innings = 5. This works NOW.

The actual length of a game has nothing to do with the either the ERA or ERG calculation. ERA is always based on 9 innings. ERA is always based on the number of Scheduled Innings for the game.

I am referring to ERG over the course of the season, not a particular game. When a season has games of different pre-determined lengths what length will be used for cumulative ERG???

We are referring to a game OR a season... it does not matter. ERG will be a weighted average. Games that are scheduled for 7 innings are calculated at 7 innings, games that are scheduled for 5 innings are calculated at 5 innings. If you want them ALL to be calculated at 7 innings, set the scheduled innings to 7, and end the game after the 5th inning for the 5 inning games. If you want them separated, create a league for the 7 inning games, and a league for the 5 innings games, and view the ERGs by league.

We are incredibly flexible in this regard... more than any other system out there and have put a lot of thought into statistic calculations.

Can you tell us any scenario where ERG would not match your expectation other than the name of it not being ERA?

Great question. I was just pondering :-)
