I once overheard Hank Haney telling a student that his swing was in so many planes he didn't know which one to look at. Ditto for the cause of slow play.
Mark Pearce- you and your mates must of the virtuous type, discussing instead the fine architectural features of the course you just played, your opponents' great form, or the great strides being made in Western Europe to curb "carbon pollution" and ensure the world's future in a more pleasing climate. My recollections of the last Buda I attended include some discussion of the pace of play at Hankley Commons and Liphook (all three rounds were played in four hours). And you only have to go into the archives on this site for like-kind references.
Brent- in golf, since the beginning, you have a few implements, a ball, and a hole. The objective, or so I thought, was to use the former to get the ball into the latter. Since I am into doing your own thing (subject most always to its effects on others), and when in Rome, do as the Romans, I have zero objections to folks picking up before consummation. In fact, when I played club golf, I feasted on the guys who picked-up the 5-footers when out of the hole and marked the scorecard as having holed it out.
IMO, the most effective way to speed up play is to create a fast-play culture at the club and to do everything possible to facilitate it through course setup, marshaling, and peer pressure. At the outset, a target pace should be established which is recognized by the members/customers as being reasonable, legitimate. Colonial CC in Fort Worth is over 7,000 yards- and the back tees do get used, is tightly bunkered, and heavily wooded. Much of the year after the NIT, the rough is long and wiry. Even during the weekend with a full tee sheet of fourball matches, they regularly play in or under four hours.
Conversely, we talk about fast play on this site till the cows come home. Yet, based on the many outings I've attended, it is mostly an intellectual exercise that has been rarely verified physically. And all of our competitions are match play.
Some of the things we can do individually to quicken the pace have been noted, but we also all need to help one another (and even other groups) to move along. Few golfers believe that they are slow. Does a friend tell a friend he is slow? Try it some time and report back.
