I just was looking at a task in Illustrative Mathematics (I use the curriculum via Open Up) where the students are asked which team improved the most. (https://access.openupresources.org/curricula/our6-8math/en/grade-7/unit-4/lesson-6/teacher.html#activity-1) Each team increased performance by 8 points though multiplicatively the improvement is very different. Three times higher score vs. 1.08 times higher score.
