That was fun! Thank you for posting that.
Interesting that the clock stops only when the cue ball stops, not when the last object ball falls into the pocket. (Evident on Shane's last rack.)
The difference was that while De Luna was racing around the table like a mad man, letting his cue ball go, Shane instead to take a few seconds after the break to survey the layout of the balls, figure out a stop-shot pattern, and clear the balls off with as many stop shots as possible. Thus, he wasn't moving around the table nearly as fast as De Luna, yet still cleared the balls off faster than him (with less misses, to boot).
