Why does the “in” hole need more room than the “out” hole in the first animation?
ETA: My friend pointed out to me that while the pendulum changes directions, the rolling ring does not. Thus it needs more space to “enter” the ring going against the movement than it does moving with the ring to exit it. It is more like the hole on the exit is standing still for the ball than it is on the entry.
I am glad that there is a reason and not just something the animator did.
