I am pretty coachable I can get often get things close to right very quickly but reliability and repeatability has always been another thing entirely. As a golfer I am pretty sure that I will always run hot and cold it is a matter of improving the cold a great deal.
I am still learning to do the drills correctly for instance I realized in the last few days that I was not doing drill number three correctly. I was moving the trail elbow too far away from the body. I seem to do a lot better if the elbow stays more in place and the hands sort of pivot around it. The elbow stills moves back and around but the movement is different. I think that the video may be a bit confusing on this drill as I think that Scott does it slightly differently when he performs the drill as oppposed to when he demos it. I think that there is a little more rotation of the upper trail arm and the elbow stays in a little tighter when he actually does the drill.
