I'm not answering for rwh, but I can tell you this:

At last year's PGA Merchandise Show, Joe Daniels, president of The Golfing Machine, LLC, hosted a gathering of TGM Authorized Instructors and 'interested others.' Chuck Cook was a featured speaker, and from the podium, he held aloft the 'Yellow Book' and said:

"This book has made me three million dollars."

That statement leads me to believe that his videos -- and I have seen none -- contain more than a little TGM.

But I also would not be surprised if, as usual...

The genius and gift of Homer Kelley remains "under wraps."

Yes, Mr. Cook knows some TGM. I've heard him speak also, and it is quite evident that TGM knowledge is there.
