Adam, I believe you are correct about the measuring standards. To say the distances haven't made as much advance as the statistics defies one's situational observations. We all watch the same toon-a-mints every year and we hear these driving distances given by the announcers, and we hear more and more guys at holes that people would oh and ah at one guy in the field hitting it 300, and now half the field does that, and that one guy is out there 360+. I think the impact of the distance technology is better observed by the yearly and situational play of the given courses and holes.
I think the main obstacle of a call to roll back the ball doesn't necessarily come from the pro and governing body in their sense or understanding of how it impacts the cost of golf by increasing the cost of maintaining and upgrading the facilities of golf. I think all the whose who in the regulation of the game know the issue. The obstacle and resistance is in the goofs like us, the consumers of these technologies of distance, who get their jollies hitting the ball 260 that can't hit it 230, and we are still playing on essentially the same tees, because 230 going up to 260 doesn't change the effective distances for the average bloke, but gives them a wet spot in their pants when playing with their buddies. So, they are the big demand behind the technology race for distance, and the pros just demonstrate the effects of that technology, exponentially. So, the average bloke pays more for their golf, even though they aren't moving back to the Tiger tees and using the facility changes effectively on their actual game, they are just paying more for the response to that distance improvement for the tiny fraction that the changes are needed. Or, another way of saying it, facility changes aren't needed for 90% of the golfing public, even if they improve distance beyond what it is here. The same blokes are going to hit it a little further but still within the parameters of 6200-6600 yards, and are just kidding themselves that their games are that much better. It is all feel-good marketing, IMHO.
