ArcMap used what I'll call, "Hard" scrolling, which means as soon as you stop scrolling on the mouse wheel, the attribute table stops moving.
I'm not sure if this is a bug or a feature, but right now in ArcGIS Pro, there is a significant delay between stopping of physical scrolling and stopping in the attribute table. This makes it really difficult to stop and view specific data, and really easy to blow past it. Not sure why this was changed?
