I have often been critical of these rankings, but there sure appears to be a trend here to getting things right. I also thank Brad for including the math, so that we can better understand the small gradations of difference when they are very small.
Rankings are mostly a way of recognizing exceptional effort, either by an owner, designer, superintendent or members who champion a restoration. What's important isn't always the exact order, but that those doing exceptional work are rewarded and may have an easier time getting more work in the future, which is best for all of us.
There is no question that Rustic is a much, much better golf course than Cascata. Is it a better experience? Probably depends on the time of day, who is in front of you, and your personality, but these are course rankings, not experience rankings.
