Actually yes :-) I run our CC's monthly Championship Tournament. Before i put it up, i play 18 holes 3 times from each of easy, hard and medium pins. Although i have now stopped doing medium after finding out they change from player to player in the same round.
When i do my practice run from each of the tees, i mark down, back left, front right, middle left, whatever the case may be.
This last month, for our April tournament on Merion, for the first time in a year playing all courses that allow for pin placement, were two pins the exact same for hard and easy.
Maybe next time i chart them out, they will change, i dont know, all i'm saying is that in my experience, 99% of the time, they are different. There is always that 1% though.
It would be great if WGT could put up a graphic of each location.
