BT43,
What is your current official number of NC courses played? Counting Extinct, Temporary, and Seasonal courses, but not counting practice areas.
My official number is maintained in my Access database, and it comes from 3 sources:
DGCR, Udisc, and unpublished Very private courses.
Udisc has more courses in their directory than DGCR, but DGCR also has some courses that aren't on Udisc.
For us old timers, DGCR will always have all of our extinct courses, so the number played may well be higher on DGCR than on Udisc. (I know that Danhyzer's and TVK's count should always be higher on DGCR.)
Unfortunately, my real number of NC courses played is not available because I have over 100 courses just to enter into my database first. From the 3 different tallies on DGCR I'm going with a conservative estimate of 320 NC courses played. I'm using 310 on DGCR + at least 10 more on Udisc and Very private. That is quite conservative.
How to count courses that are redesigned is a gray area and subjective. Even though DGCR lets you count Old layouts I take them on a case by case basis whether or not to include both. I only include both if a high percentage of the course has been changed. I do include upgrades from 9 holes to 18 as a new course. But, for example, I won't include the new UNC layout since it has a substantial number of the old holes. If I get around to playing Haywood Community College I won't include the Old layout as a separate course because there were not enough holes changed. That's just how I do it, and others will probably count courses differently.
I think that Eric V has probably played more NC courses than anybody else, but his count on DGCR is way behind, so I would like to find out from him at some point what his number is.
