4. Green speed described, compared to what we actually report
6. First sentence: “One of the most significant aspects of a golf course is the uniformity of its putting greens.”
7. Second sentence: “Variations in speed, whether from one green to the next or on different parts of the same green, can do more to negate a player’s skill than can ragged fairways or unkempt bunkers.”
