I think the post-patch park factor calculation is excessive.

Since the patch, Hall of Fame hitters have seen their WAR and WRC+ drop by more than 10 points.

I play Cincinnati and agree that the Cincinnati park factor in OOTP25 produces a lot of monster hitters, but I have a hard time agreeing that a hitter with an average OPS over 1 has a WRC+ of 147.

I also don't agree that a hitter with an OPS of 1.300 has a WRC+ of 207.

I've been importing savefiles from OOTP 25 and enjoying it. I hope you can rethink this park factor thing.

I never saw any issues with WAR previously in historical games. I saw this was changed too but have not looked at the results yet.

I have also noticed that OOTP provides a park run factor based on the BA/2B/3B/HR park factors but that estimated run factor is way off.

For example if you had a ballpark with 1.05 factors for BA/2B/3B/HR OOTP would tell you the run factor is something like 1.025, however, such a park would actually play more like 1.100. So if OOTP is using that estimated factor instead of what actually happens over the course of the season in the ballpark compared to the road games, then the calculation will always be wrong.

What park factors are set?

Sometimes Cinci's park factors can get almost to the same level you get for the Rockies, depending on what source you read from. And it can really skew things - like 2021 Chris Owings had a 1.048 OPS in 50 PA, but due to park factors only a 156 wrc+.
