Park-adjusted stats shouldn't use ballpark factors but rather observed park factors

HoustonGM · 07-23-2021, 02:31 AM

I was under the assumption that the park-adjusted stats like OPS+ would use three year park factors calculated off the actual stats, just like they do in real life, but it seems as though these stats use the Ballpark Factors from the ballpark editor. I changed factors on a park to an extreme level and it modified each player's OPS+ for each season of their career on that team. This doesn't make much sense for a few reasons, most notable being that if you change the park going forward, adjusting past stats is quite obviously wrong. I also noticed that even if you "move" a team to a new ballpark, the past stats for players of that team get modified to that new park's factor - also obviously wrong.

Has this been brought up before?

EDIT: This also results in some strange highlighting of league leading stats on player pages. It seems that the red indicating leader is stamped at the end of the season, so if an adjustment in park factors changes these past stats, you can end up with a player having a lower OPS+ or WAR than the "new" leader but with the red text still indicating they led the league.

the factors are as if we could pull back the curtin of reality and know exactly how they are defined... this is how they are defined in the model... it will be better than a 3year average... it will be absent of any human error or misperception because it is exactly how it is calculated in the game model.

** not absent.. as it is a model, the model includes that stuff inherently, but might be part of totals and not a specific part that make up the total.

Sure, I could understand using them to calculate the current year's stats. However, changes to those factors should NOT change past statistics. There's no way that makes sense.

I've seen this too. When I moved to more of a hitters park, the OPS+ of my retired batters tanked. Maybe it's tough to code/fix, I dunno. Perhaps the park adjusted stats could be "stamped" like you say.

I concur past stats should be set in stone. Probably one of those issues that so few players notice that testers also didn't notice.

Yeah definitely something that can easily be missed.

Wanted to bump this with the new release nearing

This would be a good and important change to make for ootp23, I agree

Is this still the case? Or has this been changed within the last 5 years?
