Several years ago, I was doing a pace of play improvement training and implementation program at a course in Florida. The Head Professional gave me the standard introduction to the facility and mentioned that they had a big problem with slow play complaints. He also told me that they used a 6-minute starting interval.
I hopped in a cart and set up my first observation point on the first tee. With stopwatch in hand, I started measuring the time intervals between the first players to strike a ball in each group. Knowing that a 6-minut interval is impossible to maintain, I was shocked to see that the intervals I was writing down were, "6, 6, 5, 6, 5, 5..."
"This is crazy," I thought. I then started paying very close attention to the players themselves. What I belatedly discovered was that they were all elderly retired people. In other words, men and women who were short hitters. There just weren't any "long (or longer) hitters" in the field. As a result, because short hitters don't require much open real estate in front of them, they can and did tee off when the group ahead was clear. In this case it was only about a 5 or 6-minute wait. That was lesson #1.
Lesson #2 occurred when I then drove my cart to hole #3 and discovered two groups waiting on the tee, and three groups playing the par 4 third hole which had a creek crossing the fairway directly in front of the green. Then, Hole #4 was a par 3, and there I found two more groups waiting on that tee to play. Play was indeed slow - very slow!
The reason for this story is to confirm the idea that no matter who is playing, short hitters or long hitters, and no matter what starting interval a course management team
wants in order to generate the revenue they need, the golf course itself will have the last say and it will eventually determine the proper starting interval.
This is one big reason why architects need to be careful in their routings, especially when it comes to knowing the clientele and sequencing the holes and course managers need to actively manage the first tee.
I can understand that in 1920 a 4-minute starting interval may have been possible for twosomes of "short hitters."
For those who might be interested, please read my article "Farther, Straighter, Slower" which presents my view of the unintended consequence of unbridled technology and how hitting the ball farther is making play slower and starting intervals longer. You can find it on my website
