I am not sure how I feel about this special formula for the US Open rough.
Why make the easy holes harder and the hard holes easier?? If that happens, wouldnt the intent of the hole be lost?? For instance, there are certain holes that are supposed to play harder then others, such as long par 4's. If you take away some of what makes the hole hard it is just a regular hole for the tournament. The same can be said for the short holes, such as reachable par 4's or 5's. Those are supposed to be the scoring holes, and if you make all the holes play equally challenging by mixing up the rough then that certainly does not add anything for the course, in my opinion.
Anywho, thanks for that though Pat, it is certainly interesting.
