I added the underline above.What part of the ball, the bottom, the equator, the top? Or, put another way, after defining which part, how far below the surface of the fairway? I just cannot see a way that one can define these abnormal ground conditions such that fair and equitable relief is given to all and not open to interpretation from one instance to the next. The only solution would be allowing one to pick, clean and place the ball in the fairway all the time and within a specified distance of the original lie since there is the the expectation that being in the fairway should always result in a perfect lie.
Golf isn't fair, and Lee Westwood said so himself this week. It is meant to be equitable. As unfair, and unjust, playing from an unrepaired divot may be, it is unfortunately the most equitable way to do it.
