I would like to add that Riccio addresses specifically "perceived" pace of play and "actual" pace of play, and treats each differently.
https://www.golfsciencejournal.org/article/4965-analyzing-the-pace-of-play-in-golf-the-golf-course-as-a-factory"Even if all groups are “fast” but experience some time/shot variability, even if the overall pace is quick, most groups will experience some waiting and will perceive that the pace is slow."
The one section that I think can illustrate this is the following figures in the paper:
Figure 11 — One day all fast groups with modest variability.
Figure 12 — Each group’s total waiting time.
Here, we see that *all fast groups* end up creating slower play through the day. More striking is figure 12, where, during the day, *actual wait time* varies dramatically, even if overall pace does not.
In the research, it seems that confounding variables are generally overshadowed by tee-time interval, with a few exceptions. Yes, set up time is the most dominant factor for individual pace, but placement of par 3s and reachable par 5s matters as well.
Granted, the actual play time of all the twosomes could be shortened dramatically if there were some type of shot clock, (this data is all from modeled foursomes i believe), but since the tour has access to player set-up and pace, they could easily model out event days to try and choose and ideal tee time interval for each group (even getting into player specifics). Since we have computers, there is no reason why every tee time interval MUST BE THE SAME. If players have longer set ups, then give them a shorter gap as the start, if players are quicker, then give them a longer gap.
I find the No Laying Up article to be looking for a solution far-far away from where the research lies. Players can play at their own -- reasonable -- slow pace, and the tournament can easily be set up to suit them. At the end of the day, if Cantlay waited on the 18th fairway, which he apparently did, then all the hemming and hawing about a 45 second setup, while ridiculous, is missing the point. The real solution is dynamically assigning tee time intervals to better keep the wait times down between players. This can happen both at the start of the match, and at the turn.
(again, this is my first series of posts here, so if the images there are huge or don't work, i'm sorry)
