Dave:
You think what the rules expert said sounds like "goofey talk"?? How about what you just said there in that last post?!!
I have no real idea what you're trying to say or mince there.
Just look at it this way if you didn't realize this. Often, in rules applications various situations as they apply to various rules are considered separate situations unto themselves with a beginning point and ending point within an ultimate resolution. These guys apply them that way and don't jumble all possible rules as they might affect the ultimate outcome together. You saw what he said there about "items" and "properties" of various situations--that's probably what he's talking about here of using the original GUR boundaries to establish the NPR and then using that reference point for the drop even if the GUR is not longer there. Do you notice how he mentions both "equity" and commonsense when these items and properties show no precedence about what should come first?
This probably isn't all that different from a situation where you have a drop away from an immovable obstruction and that lands you with a proper drop in casual water. You do the one first and then the second separately and second, you don't just jumble them together, although in some circumstances you actually can if it's obvious and makes commonsense.
But if I'm reading correctly what he's saying about this hypothetical of yours the spot you think you can drop is not the correct one. You have to use the reference point of the NPR just as it existed before the GUR was removed. The reason, again, he uses, is equity. And he's the guy who writes a lot of these rules so if you don't agree with him the only thing to do is to write the Joint USGA/R&A Rules Committee and appeal it to them---but I don't think that'll work well as he's one of the guys who'll review your appeal. And if he's the one who instructs you to do it this way on the course you better do it his way, not your way unless you like penalties.
What he said makes perfect sense to me although at first I wouldn't have expected Rule 25 to be so controlled in this situation by Rule 23, but I can see now why it is---and matter of fact vice versa---how the Rule 25 GUR reference point controls even when the GUR has been removed.
