Bryan,
We have discussed it before, and I don't have time to get into it in great detail right now, but I will try to later.
The USGA study established nothing more than that they themselves have no concept of the problem that the new balls have created for golf. They set up then disproved a few overly simplistic claims, but in the process they completely ignored the real problem.
In essence, the USGA proved what most high school physics students could probably guess at. For a particular golf ball the distance gained by increasing swing speed from 110 to 120 mph will be less than the distance gained by increasing the swing speed from 100 to 110 mph.
So, for example, BALL A gained about 34 yards when swing speed was increased from 90 to 100 mph, and about 31 yards from 100 to 110 mph, and increased just under 25 yards when swing speed increased from 110 yards to 120 mph. So, FOR A PARTICULAR BALL, incremental increases in swing speed DO NOT result in disproportionate increases in distance gained. Fine. That makes perfect sense. It is not accurate to say that the ProV1x suddenly is activated at 110 mph.
However, this entirely misses the issue. As understand it, the issue is: DOES THE NEW BALL TECHNOLOGY DISPROPORTIONALLY BENEFIT THOSE WITH FASTER SWING SPEEDS? The answer is YES.
[I know some of you are thinking But you just agreed with the usga that the answer is "No." I haven't. It is difficult to understand (apparently too difficult for the USGA) but the study and result above doesn't even address this issue.]
In order to figure this out we must compare driving distances of the new balls at various swing speeds with BALLS WHICH WERE STATE OF THE ART BEFORE THE INTRODUCTION OF THESE NEW BALLS. That way we can look at who has benefited from these balls and who has not. Also, we need to keep in mind that, for most golfers, swing speeds can't go much higher. I can't rev my swing speed up to 120. What matters for me is, "With my swing speed, does the ProV1x go further than what I could have bought before." The answer is obviously NO.

A hypothetical using three balls and three golfers, and two jumps in ball distance technology . . .
The BALLS: the PRE (representing the state of the art before the first tech jump, when new balls took over), the V (representing the first generation of these new balls), and the X (representing the second generation fo these new balls.)
The GOLFERS: EIGHTY, HUNDRED, and ONE-TWENTY, named after their swing speed.
- EIGHTY hits the PRE farther than the V and a lot farther than the X.
- HUNDRED hits V a lot farther than the PRE and farther than the X.
- ONE-TWENTY hits the X a lot farther than both the PRE and the V.
What has the technological boom done for EIGHTY's driving distance? NOTHING. The first tech bump hurt EIGHTY relative to the others, and the second bump hurt him more. (If he can no longer find a ball similar to the PRE and must play something like X or V, then his actual driving distance decreases in real terms, and his relative disadvantage to the others grows even greater.)
What has the technological boom done for HUNDRED's driving distance? The first tech bump gave HUNDRED a disproportionate advantage over EIGHTY, compared to where they were before. (But the second Tech bump put him at a relative disadvantage to ONE-TWENTY.
What has the technological boom done for ONE-TWENTY? Relative to the state of the art before the advance, ONE-TWENTY HAS REAPED BIG BENEFITS over the other two.
So if PRE has gotten no benefit from the technological advances, and ONE-TWENTY has reaped huge benefits, then how can the USGA say that "there is no extra distance bonus for high swing speeds." Well, they can't at least not if they want to correctly state the current circumstance. But the reason that they do so is that their study was asking the WRONG QUESTIONS.
The USGA focused on how each particular ball behaved as swing speed increased without COMPARING HOW NEW BALLS BEHAVED COMPARED TO OLD BALLS. So, the USGA told EIGHTY, HUNDRED, AND ONE-TWENTY that if they ALL PLAY THE ProVIx, the distance difference between HUNDRED'S drive and EIGHTY's drive will be slightly larger than the distance difference between ONE-TWENTY's drive and HUNDRED's drive. But if I am EIGHTY that is of little comfort, because if I PLAY THE ProV1x then I take a huge hit to my distance compared to what it was before! I lose ground while they gain ground, because I don't swing fast enough for the ball to work for me at all. And it sure is heck seems like they have received a distance dividend that has passed me by.
_____________________________
The USGA's own numbers more than hint at this glitch in their study. From 90 to 100 mph, the distance increases 34 yards, or 3.4 yards per mph. As we go down in speed we will lose slightly more distance per mph (this is the corollary of gaining less distance as swingspeed goes up. So when we drop from 90 to 80 we lose more than 34 yards, and if we drop to 70 mph we lose at least 102 yards and probably a bit more.
According to the study, the distance of BALL A at 90 mph swing speed was about 220 yards. So for the 80 mph swing speed, the distance is less than 186 yards, total driving distance. For the 70 mph swinger, the total distance is less than 153 yards. AND THESE NUMBERS ARE PROBABLY TOO LONG, BECAUSE THE USGA HAS PROVEN THAT INCREASE IN DISTANCE PER INCREASE IN MPH TAPERS OFF AS THE NUMBERS GET HIGHER (THEREFORE THE DECREASE MUST GROW AS SWINGSPEED DECREASES.
Does anyone think that someone with an 80 mph or 70 mph swing speed has gotten any more distance out of the technology behind this ball? Even the golfer with a 90 mph swing speed is only driving it just over 220 yards total with this technologically advanced ball. Meanwhile those with swinging it 125 mph are hitting it 320. So a golfer with a swing speed of 90 (which used to be a respectable swing speed) is almost 100 yards behind those with faster swing speeds.
I don't have great numbers for the old balls, but I think I may have some somewhere and I'll try to find them later.
NOTE: EDITED TO CORRECT SOME ERRORS IN THE NUMBERS.
