Stu1961 I don’t mind the shotgun start, nor the added team aspect. Shotgun is just one step further along the line from tournaments that already start groups off both the front and back. Advantage would be in both reduced TV time, but also far less chance of situations - which I really hate - where half the field gets completely different conditions based on their tee times.
There's a limit to the number of players that can be on the golf course at the same time, and most tournaments have fields that are close to double that number (156 is fairly standard, which is 2 waves of 13 three-balls off the 1st and 10th tees) - using a shotgun start in a 'normal' tour event would reduce the time that the course is in use a little bit over a two-tee start, but you would still need to have two waves of players, starting around 6 hours apart..
The simplest way to reduce the amount of time that players are on-course is to make them play faster...
