Occasional Tour Caddy
About 20 years ago when we had a problem with slow play we extended the tee times to 10 minutes.
It worked a treat. The biggest problem was with the starter holding groups up on the first tee. It was 510 par 5. Normally players would drive off as soon as the match in front were out of range. This sometimes led to two groups of players within 50 yards of each other waiting on the fairway with the match on the first tee also waiting. The starter would hold the players on the first tee. until the players in front were within 50 yards of the green.
One problem was that as it was a busy course with over 1000 members at least 30 players were excluded from every medal
Re 10 minute spacing. I've read this a number of times and everyone seems to agree that it works well in improving overall round duration and general pace. Its a wonder more course don't/wont do it
Re my bold. I believe from what I've read that if the original format of spacing at 7-8 minutes didn't also have a 'blank' or spacer group each hour (effectively a ghost 4ball) that the number of tee times lost were noticeable as opposed to about the same capacity available if a spacer group was used
Basically if moving from a pack em, rack em & stack em format then its tougher to go to the 10 minute spacing but still beneficial
