During a typical round of golf dozens of opportunities to save a few moments slowly vanish. if I had to choose to play faster golf or slower golf I would choose faster golf. How you answer that question tells a lot about your own pace of play. Most of the time I have no choice and play slower than I want. I LOVE TO PLAY GOLF PERIOD. I do not believe slow play depends on the course, the size of the group or even the time it takes to play the round. If your playing partners take practice swings then it is going to be a slow round. If everybody needs to comment on every shot right after the ball is hit then probably a slow round. If your playing partners never putt out because one time they missed a short putt instead of marking and waiting until they are out again then it is going to be slow. If your companions always bring their putter head cover to the green then they are slowing you down. If your preshot rountine starts with putting a glove on then your thoughtlessly slow. If you cannot drop off your cart companion and go hit your shot then meet in the middle afterward then your playing golf by the hour and not the job.
Justice Potter Stewart's famous phrase "I know it when I see it" the constitution protects all golf except "slow-core golf" ......But I know it when I see it
