Some observations:
-There's nearly been a 50% turnover in the list (45 out/in)
- 21 "New" courses built have entered the current list. Of those only 7 are in the current Top50 and 2 in the Top 25 (Sand Hills and Pacific Dunes)
- Biggest movers up = Fishers Island (+55), Morfontaine (+53), Somerset Hills (+47)
- Biggest movers down = Baltusrol L (-76), Harbour Town (-72), Oak Hill (-67) & out of Top100
- A lot of "classic" venues have entered the list particularly from GB&I
- A fair few PGA Tour / Manjor venues have moved out of the list
- The mix has changed somewhat with USA down / GB&I up roughly around 10 courses
- Clearly- template hole courses weren't appreciated back in the 80's (see NGLA / Fishers Island / Chicago)
