Just4me has said that defensive proficiency begins to drop as soon as 99% but hitting is less prone to tapering off to 90% or below, that some of his best performances were 93 or below. Ideally you don't want to buy more than you need. I would probably start off with 640-650 in a neutral park for the top 2-3 lineup spots, adjust downward a bit for the others. Shave off what you don't need in subsequent seasons. Trial and error is needed here.
Those are probably conservative numbers, you could try 5-10% less, see how it goes. Open leagues are a good testing ground..
I've used '80 Dilone or the 542PA McGee in a top 2 in the order without serious fatigue issues. Perhaps bat them 8th or 9th occasionally to give them a bit less exposure.
This is mostly correct. Fatigue impacts all facets immediately, but because of how the math works, it’s less noticeable on hitting performance than fielding performance. And for pitchers, you can control some of the most impacted variables with ballpark and defense choices to minimize those impacts, as well.
For example, .300 AVG at 90% = .3*.9= .270. Throw them in a +1B ballpark and the effect of fatigue will be even smaller because the ballpark is boosting the hits up even more.
.230 OAV at 90% = .230/.9=.256. Throw them in a -1B ballpark and reduce that further. Put A+ range behind the pitcher and it’s like he’s not fatigued at all.
.990 FLD at 90% = .99*.9=.891. Your only chance here is if it’s a modern pitcher and a modern hitter to not reduce your starting FLD even more. But you’re hurting no matter what.
The hitting and pitching stats are all derivative of AVG/OAV except for BB rate, so you can get a rough idea of the fatigue impact ahead of time.
