I think there's a lot of value to considering the spacial distortion at a time bubble's edge!
We know that object that cross that boundary change have their trajectory affected (which is why you can't accurately shoot out of a time bubble, your aim gets thrown off). This reminds me of light bending as it enters water.
Also, I really want to re-read the last chapter of AoL, when Wax shoots his own bullet to change it's course.
When I first read it, I pictured Robin Hood shooting his own arrow (that happened in the disney cartoon i think?). However, I think there's something important there about projectile physics. Specifically, how did the second bullet catch up to the first one? AFAIK, Robin was able to do it because the arrow's original trajectory was vertical (his first shot was high). Bullets leaving a gun barrel should have the same velocity and therefore shouldn't be able to catch up.
