> Golf is not so smooth. Yes, each round is a state-dependent game of error-correction (i.e. Zeno's Paradox). But golf swings are coarse actions -- few swings per game, with no recourse for fine adjustment between swings.

This is a bit of a contradictory statement. The "error-correction"'s are typically fine adjustments between swings. Small adjustments to setup, backswing, tempo, etc. are exactly the sort of thing a golfer adjusts during a typical round.
