Would you or your fellow players know if ZiPS at least uses a standard (as opposed to actual) left/right differential for players, or if the split is exactly the same left and right?

If the player records on the ZiPS Projection disk were created using the "Overall" method, which I think we can assume, then DMB would "use historical norms to rate batters to perform better against opposite-handed pitchers. The difference is about 20 batting average points and 30-40 points in slugging average. In other words, a lefty hitter who batted .280 overall would be rated to hit about .287 against righties and .267 against lefties. If that player faces righties about 2/3 of the time, his overall average in his DMB games would be around .280. Similar adjustments are made for right-handed batters and for pitchers."
