Hit Modifier test league discussion thread Topic

We are talking about having a test league to find the true meaning of hit modifiers, and their effects on singles/all hits...

Agreed a test league wouldn’t give 100% clarification, but similar to how contrarian’s twisl in regards to k’s and + plays, It may not solve it 100%, but definitely adds some clarity.

I would definitely be interested in a theme like that, as long as it was put together properly. Dodger stadium in the NL, exhibition stadium in the AL, see how hits add up over the course of the season. Not concrete, but 3888 games of data is always beneficial.
Exhibition Stadium is much different, very xbh friendly. I was thinking of a comparison of Dodger, Shea, and perhaps Network Associates... Qualcomm as a 4th, 6 of each, 1 per division?
I know many don't like an identical roster, they prefer to pick their own. Perhaps I just post some perimeters as to how they must draft, leave them to their own demise... how's about $90M cap, a team aggregate whip of 1.00 or less, a minimum of 1,250 innings to prevent fatigue spiral...

To test ballpark effects in a test league setup we’d need two test leagues each running the same roster. each league with two parks and setup with two of each park in each division. League one would have two parks that have different (opposite) 1B modifier, and identical XBH modifiers. League two would have same 1B modifier and different (opposite) XBH factor (pick 1, doubles or triples would be best).

Using the table linked previously, we can estimate the AVG and XBH rate in question for the hitters as a prediction towards the hypothesis by using the log5 formula with the ballpark modifiers for the hitters/pitchers chosen across the four ballparks for both theories (1B = 1B and 1B = hits).

Obviously, a little luck could swing some of the results, but over that many games we should be fairly close and see a result that gives us a solid indicator of which is correct.

Or, admin could give us both the exact effect modifier and where it falls in the tree...

I’m in for however many teams needed...

to isolate ballpark effects more we could limit identical players to the same season/league so normalization isn’t a factor and minimize the luck/noise

but, the more restrictions the less likely we are to find participants...

I think those are excellent park selections overall, though might want to see a
toich more separation on the first one. Especially with rounding and cut offs the exact modifier difference between that -2 1B and -1 1B might be just a couple hundredths, and hard to see any value on. I’m on mobile right now, so searching myself is a challenge, but love the second set for sure

I'm open to suggestions on rosters, but they should be competitive. No reason to build a roster that mails it in come TOC time...

Interesting discussion and was interesting reading in the other thread. I think that if you test a park against something other than WIS stadium you run the risk of muddying the waters and making any conclusion more difficult

I think for the discussion, it would be helpful to have a "opposite end of the spectrum" league.

Dodger Stadium
+2 -4 -3 -1 -1 0.87

Safeco Field
-2 -2 -1 -2 -2 0.88


Given that the discussion is surrounding dodger stadium and whether the 1B modifier is referring to hits or singles. imo this would give a better idea as both are negative xbh, but dodger is +2 1B, Safeco is-2

Maybe it’s just me, but the parks in each league seem way too close to draw any meaningful distinction. For example, for League 1, wouldn’t you want parks that have a huge gap in their 1B rating and are close in everything else?

For example:

Ameriquest Field: +2 +1 +2 +1 +1

AND

Exhibition Stadium: -2 +2 +2 +1 +1

We will get a more accurate picture if the parks are similar.
