I say modified because I prefer a decimal system to indicate which way you are leaning...for your pleasure here are a number of Doak rating criteria from 5 to 10...
5. Well above average golf course, but the middle of my scale. A good course to choose if you're in the vicinity and looking for a game, but don't spend another day away from home just to see it, unless your home is in Alaska.
6. A very good course, definitely worth a game if your're in town, but not necessarily worth a special trip to see. It shouldn't disappoint you.
7. An excellent course, worth checking out if you get anywhere within 100miles. You can expect to find soundly designed, interestiong holes, good course conditioning, and a pretty setting, if not necessarily anything unique to the world of golf.
8. One of the very best courses in its region (althugh there are more 8's in some places, and none in others), and worth a special trip to see. Could have some drawbacks, but these will clearly be spelled out, and it will make up for them with something really special in addition to the generally excellent layout.
9. An outstanding course--certainly one of the best in world--with no weaknesses in regard to condition, length, or poor holes. You should see this course sometime in your life.
10. Nearly perfect; if you skipped even one hole, you would miss something worth seeing. If you haven't seen all the courses in this category, you don't know how good golf architecture can get. Drop the book and call your travel agent--immediately.
