Sean,
In principle I can understand your reasoning, but if the reason you are visiting a particular course is to to give it a rating that allows it to be measured against others as to greatness (i.e. - 100 greatest, etc...) than to do as you suggest is unfair to the course you are at and all others who are being rated for this purpose.
I think it is greatly important that those who rate courses for different journals need to be on the same page as to what should be examined and why. The closer to having a consensus on this the more fair and correct the rating process becomes.
For example, like the standards set by Golf Digest or not, if someone decides that the price tag to play Pebble Beach is so extreme that it takes away from "ambience" might be understandable. Taking it away from "conditioning" is not.
If the purpose of a rating is to measure course design greatness vs. affordability (e.g. - Best Bang for the Buck) go ahead & apply the principle, but to judge a course's value as better or worse simply on the basis of price structure, I believe does a disservice to the magazine one is rating for and their readership.
Oh yes, and for those raters who haven't looked at it - play BETHPAGE RED! You will be stunned by it.
