The arm holding the cup has the remarkable ability to act as a shock
absorber for the rest of the body and minimize the motion to the cup. I
find that it helps when you watch the cup carefully. If it starts
sloshing, you can adjust.

With practice, you can be almost as good as a chicken:

Now that I have your attention!

I see faculty walking past my room with their coffees every morning. Is
there an optimal walking frequency (speed) to minimize the liquid from
sloshing back and forth and spilling over? I imagine this depends on the
leg length, diameter of cup, depth of cup, etc.

P.S. I've never had coffee, but I'm curious about this sloshing phenomenon.
