Interesting article explaining why leaving the flagstick in will result in more putts missed. The science in this article makes sense to me and I’m glad someone took the time and effort to use the scientific method to measure this.
A quote from the summary section:
“Leaving the flagstick in may have some benefits but from a physics standpoint, there is zero evidence to suggest that the flagstick helps in any but the rarest of situations. What the flagstick may do is occasionally reduce the length of a second putt and therefore possibly help reduce three-putts. Of course, it also will clearly and substantially reduce the number of one-putts. It’s also clear from our research that the fiberglass type of flagstick is the least detrimental (but still nowhere near as good as taking the flagstick out).”
