In all honesty Gary, I hit a few dozen shots before a round, usually 5 irons. My ball flight tells me how my swing is doing as well as my balance at the finish. I'll hit a few fades, draws, high and low trajectory shots. Not saying videos are not helpful, but after 60 years of playing this great game ,before videos and rangefinders, I keep my handicap under 10.

Derek, I'll go out on a limb and say, even if the masses wanted to see a video of themself, most would not know what to look for, what was good, or what needs changing. Also, video yourself is at a level of commitment that I don't see from most of the people that show up to golf that I see on the course anyway. Many golfers won't go get a basic lesson. They show up to the course, and just want to get to the first tee as quickly as possible. It seems most don't even hit a bucket before they go play a round of golf. Shoot, in my last round, I was taking a few minutes to stretch while waiting to tee off and a guy in my group asked why I was stretching.
