IRT to the golf video. They are using computers to optimize their every movement. What's surprising to me is how close the one golfer is able to call out the distance of the hit. Average Joe doesn't use all of that equipment, and I think it does well to consider how far and accurate Joe would hit with a putter and compare that.
To top it off,
golf handicap seems to depend on the course, so it stands to reason that the 16 average isn't as dependable as one would think because that is an average for all courses.
I'm guessing that a PGA-level course is much harder than the local course at the state park, and probably more difficult than than the average country-club course.
The analogy would be from bowling (it was like poker-level TV stuff in the 90s). The waxing on your local bowling alley isn't the same as the waxing in the pro circuit, which effects the average score. I'm not sure the exact numbers, but a professional has an average of say, 175. If someone has an average of 175 in the local league, he would have an average of 125 on a professional lane, which would certainly disqualify most local heroes from going pro.
Point being, the venue would have to play a major role, so I'm guessing a handicap on a PGA-level course would cause a 16 person to be closer to 20 or possibly 30. Even if the 16 person picked the venue, the under for the professional would probably be higher as well, though I suppose there is a smaller difference going negative than positive.
