First - I am not a teacher of the game. I am not a golf professional and have no monetary interest in any system of golf or golf teaching. My 'knowledge' of golf is purely based in facts and science which are available to anyone that cares to do research and is hardly unique or inaccessable.
The archives of this forum are full of examples of pros who, for whatever reasons chose to claim they used a particular system of golf (note that I said 'used a particular system' NOT were taught by certain people) but even moderately close examination showed they did not exhibit the specific characteristics associated with that system of golf as marketed to the general public. Given that the system was clearly trying to claim benefits by associating itself with said pros there was clearly a 'bait & switch'.
Examples include Jerry Heard of the Heard Super Swing (HSS), Craig Bowden with Natural Golf.
As a result of these and some other experiences I look to whether a pro 'walks the walk' AND whether their statements make 'physical' sense (as in are scientifically correct). Even if a pro believes what they say 100% it has to be taken with considerable salt if it does not match the physical reality. An example of this is the debate a while back about 'pinching' the ball on a shot. There you had a professional golfer & instructor claiming that the ball was actually 'pinched' between the club and the ground on a shot even though high speed video shows that it is not.
When statements by a pro do not match the physical reality that does not mean they should be dismissed out of hand (at least not when there is no financial incentive) but rather that they need to be interpreted as more of a 'feel' or koan. Hogan's statment about hitting as hard as possible with the trail hand is an example of this given what is seen in video of his swing.
It is fine for Bennett and Plummer to claim some share of credit for the performance of pros they are teaching and that might well encourage people to go to them for instruction (as has been true of Ledbetter, Harmon and others) but it is quite a different thing to claim those pros are using S&T when they don't exhibit the S&T fundamentals as packaged in their real swings. Some of the pros clearly know the difference when they 'tilt on the backswing' in the infomercial but not on their real swings in competition. This makes it clear that the difference is NOT due to the physical characteristics of the golfers. If physical characteristics were a source of difference in these fundamentals then the explanations should make it clear. There are systems of golf that explain explicitly that different body types require different swings.
The over the top notes about 'no disrespect' are not necessary. Simple recognition of objective facts and a civil conversation are all that are necessary here.
Charlie Wi does not 'tilt [towards the target] in his backswing as Bennet says is the foundation of S&T and this was the source of my original statement. Recognizing that it was clear that Charlie did not do this, one on the other side of the discussion first asserted that Bennet did not say you should do this. They suggested that the infomercial was not a 'good' source of information and that there were much better videos available on line. I have now quoted from another of those 'better' videos on line where Bennet (as I've said I like to work from original sources) specifically explains S&T and explicitly says you should tilt [demonstrating towards the target] on the backswing.
These are just the facts. I can think of any number of reasons why, when teaching a sport, you might advise someone to do something that you do not want them to do in reality but none on the other side of this discussion have admitted that was the case (as another 'system' creator has here on a similar issue which fully explained a key element of the philosophy of teaching in his system).
