Occasional Tour Caddy
I dont get the difference in teeing off behind a slower group whether it's at 8 mins or 10 min intervals.
If they are slower than my group, we are still going to catch them up and have to wait. It just means we'll catch them up on the 3rd tee and not the second
Similar principles to motorway driving, the better the spacing the more consistent the speed & the overall journey time is reduced
