From what I've read and observed, the golf swing takes 0.8-1.2 seconds from start to impact. It takes 1/3 of a second for your hands to send your brain what they are sensing, 1/4 second for the brain to interpret the information and another 1/3 of a second for your brain to send information back to your hands. ....
Kills me when Tiger says that he gets stuck and "saves it" as if he gets halfway down, realizes and save it. Proably the "get stuck and save it" pattern is triggered no later than the End and perhaps sooner.
