(W) Rotation gives wild manual rotations

I'm using After Effects 2020, and when I try to manually rotate an object around its pivot in the viewport, the object rotates in wildly large increments. But when I drag and slide in the Rotation number field in the timeline, I get a finely controlled micro rotation. Why does the manual rotation using (W) flip out with large uncontrollable rotations, and is there a way to modify its sensitivity to my mouse or pen movement to give me the fine control I am looking for?
