I'm curious if any of the media teams have figured out if there's any course fatigue where viewership has gone down in the following year(s) on a course even if the groups playing them continue to be top rated.
I think proving that correlation would be nearly impossible, as it connects an assumption (course fatigue) with an action (delta in views). Even if you found a tournament where viewership decreased, you'd have to interview the people who didn't watch to confirm their reasoning, and since we don't know who those people are I don't see a way to conclude any intention.
The best you could do is to look at the "tail" of the videos year over year - after the initial spike in views when it's fresh, how steep is the slope of the decline after 3 days? After 7? After 30? etc. You'd then have to control for increase in subscriber base in the preceding 12 months. You'd then have to find a way to weed out whether it was due to better crew, better techniques, etc.
Basically, I don't believe we have the data to give an answer with any real degree of confidence, though at the same time I do recognize that our courses are the weakest part of the tour.
