Matt,
I have no problem with you saying that, most of what is said on here is just someone's opinion. Of the courses we've both seen I tend to agree with your comments more often than naught, although not always. It is what it is.
To protect the innocent
(meaning not using any specific course as an example) here's an example of rating competing courses.
Mr. Doe is a rater and member at course A in a medium sized town with two good golf clubs (A & B). The two clubs have a fairly intense rivalry being on the opposite side of town and are always trying to "one-up" the other. While not the only factor, the clubs always want to be the higher rated club in the various publications. Mr. Doe as a rater can affect this in two ways, rating A highly and rating B lowly. Both could skew the overall ratings.
Now...there's no way to measure what a "competing club" is either. I certainly hope this doesn't even happen, but I'm cynical to think it probably has somewhere, just as courses are likely propped up with their "WOW" factor with first time visitors. I'm just trying to point out that the idea of having local raters with added weight of state rankings has a hole or two it IMO. Maybe the current format balances things out, maybe not, but I'm not convinced there is a better way.
EDIT: In my effort to be detailed Jim made my case in about two sentences
All I was pointing out was that not rating one's own course is hardly the only way to influence its position.
