Fwiw, I recall reading an interview with Curtis Strange where he said his 62 on The Old Course was no longer recognized as the record, due to many changes, and he was pretty ticked.
Tough call, it's pretty easy to see both sides.
As an aside, wasn't the World Cup event in 2003? I recall the date rather well, as the course was closed during my only visit to Kiawah, something I hope to rectify someday. Was there another World Cup at Kiawah in 1997?
EDIT: just googled it, it was indeed at Kiawah both in '97 and '03.
