In support of my contention that even a mediocre golfer can benefit from knowing the distance to the hole, I sat down after each of my rounds this weekend and made a list of the distances of wedge shots I faced and the length of the resulting putt (or in one case not a putt, alas). I used a SkyCaddie GPS in my customary manner, strapped to the handle of my push-cart where I can glance at it as I pull the club. Keep in mind that I just looked at front/center/back distances and had to eyeball where the hole was located relative to those references.
Saturday
37 yards in Fairway to 4 feet (left), 1-putt
69 yards in Rough to 1 foot (short), 1-putt
104 yards in Rough to 48 feet (long right, above the hole), 2-putt
83 yards in Fairway to 8 feet (left), 2-putt
39 yards in Rough to 14 feet (long, above the hole), 3-putt
66 yards in Rough to 32 feet (short, below the hole), 2-putt
88 yards in Fairway to 16 feet (short left, above the hole), 3-putt

110 yards in Rough to 22 feet (pin high right), 2-putt
93 yards in Fairway resulted in chunked shot missed green

Now this was a weekend of hitting good wedge shots by my standards. But I'm now more convinced than ever that it makes a difference knowing the distance plus or minus a couple yards by using some sort of yardage reference. At those distances if I relied on just eyeballing the total distance, I doubt I'd be within give or take even five yards more than a couple times by accident. But an awful lot of those shots (nearly half) ended up within four yards of the hole.
