This is solely a question about counting how many courses I've played on a Top 100 list or that kind of thing.
After a renovation, when do you say that you've no longer played a course?
I played Inverness in 2000. At this point, I'd say that I've played it. What about after they open three new holes? Will I still say that I've played it when it appears on the next Top 100 list post-renovation?
If a course renovates all of its bunkers, you've probably still played it (ex., Olympic Lake 3 years ago vs. now). What if it adds a bunch of bunkers — I played Baltusrol Lower in 2000, too. Do I still count that one?
If you played MPCC Dunes course 5 years ago and then look at a 2017-2018 list, do you still count it as one of the Top 100 courses you've played?
Solely for counting purposes, where do you draw the line?
