What do I think? To this point we've been happy to let everyone form their own opinions about the "correctness" of the data in the S&T 2.0 DVDs… But since you asked, and in case it's not obvious already:
- We think that the 81% above is highly inaccurate; not for weight, not for pressure.
- We think that implying that if a golfer gets his weight farther forward he can hit it farther is not going to serve golfers well, particularly when long drive guys (who care quite a bit about hitting the ball far) are far more likely to put weight and pressure on the trail side (largely so they can generate a positive AoA - they still transfer some pressure forward in the downswing).
- Troy himself said in the video that he "felt like it was 65/35" and immediately added "but it probably wasn't that high."
- "Measurable facts validated independently" is not an accurate statement if the data itself is not accurate. If someone tells us that he's verified that the value for g (~gravity) on the surface of planet earth is 1.4 m/s^2, we aren't going to believe him regardless of how much "data" he has to back it up.
- Troy toed the ball, which helped it draw. Minor point not really worth getting into - it still would have drawn with centered contact, but it could have easily cut if it was hit just as far on the heel as it was on the toe.
- This wasn't the fastest clubhead speed recorded. See above. Small point (0.4 MPH worth).
This image demonstrates why we believe one should be very careful when presenting data, particularly when it's used in cause-and-effect scenarios.
The premise here is that the more weight you put forward, the more you can "crush it." The problems are two-fold, in our opinion:
- The data itself is not trustworthy. It's highly unlikely Troy is 81% forward with weight or pressure:
- A clear cause-and-effect relationship has not been established. Troy would need to hit many golf balls, varying weight locations but controlling virtually all other aspects of his swing and impact conditions, to begin to "prove" much of anything in this regard. And as we know, hitting up with the driver produces longer tee shots than hitting down, and so one could easily make a logical argument that even at the same clubhead speed - even at a slightly reduced clubhead speed - Troy could hit the ball farther with his weight back slightly to allow him to hit up on the golf ball.
We have seen several comments from S&T instructors that indicate that they are either not questioning the data shown in the S&T 2.0 DVDs or simply believe it to be accurate.
Truth be told, we don't know what to say about that. We think the information, photos, etc. above are fairly compelling.
