Mike,
I have told this story before, but my wife (a hundred plus shooter) and I (I shot low 80's) played RM three times over two days a few years back, and never exceeded 2 hours 45 minutes for the round. On one round, we teed off just after the ladies league, so they played at least that fast as well.
I think, based on that experience, that RM should be the prototype of a golf course that is both challenging enough to be ranked in the world top 5 by about everybody, and still be fun and fast to play. I have given it a lot of thought since then.
Certainly, we didn't spend time looking for balls, and that is a huge part of it. The proximity of most greens and tees, I feel adds to speed of play. It does take 15-30 seconds per hole to walk to the next tee, and the difference in a longer distance adds at least 10 minutes to a round.
Another factor is that they allow the "trolleys" or pull carts right up on to the collar of the green, which amazed my wife, without ill turf effects. I think the time of walking from the cart path (in America) or the bottom of the bank elsewhere must add another 30 seconds per hole, if not more. There goes another 10 minutes. In America, that cart path is farther away than the nearer toe of slope on older courses like RM, and it seems the larger scale of modern courses adds a few minutes to the round.
Add in that RM usually has you walking ahead, not back or to the side, which allows the next group to play quicker.
All the things Tom mentions may be universal. But, ther RM greens were anything but easy to putt, and we still played fast. Lastly, in many casual rounds, playing partners graciously concede the third putt to avoid seeing a grown man cry anyway.
I think Craig hits it on the nose about not being ready to play. I think cart use, even when allowed anywhere on the course slows down play further. Not only does your cart partner watch you play, but he waits for you before driving to his ball. Then, he forgets which tree he lined up on, necessitating a brief search (usually an optimistic 50 yards farther than he actually hit the ball
, and THEN he starts planning the shot, tossing the obligatory sprigs up several times to test the wind, looking for yardage markers, agonizing over a six versus a seven - when it should really be a five or four
, and so on. Then there is the post shot "I didn't really catch it well" when in reality, the seven he chose was the flushest shot of the day, but naturally ended up about twenty yards short!
I always try to drop off my cart partner, if I am a suitable distance away from his shot to get a head start on play, but it's not always possible, and I am sure we are all guilty of this on more than one occaision when playing with carts.
I'll stop venting now, and go to church to pray for the sinners - and slow players, but not necessarily in that order!
