In addition, you have a lot of golf instructors that know a lot about the mental game and they're talking a lot more about the mental game to their students. I've worked with students as young as nine years old, where their father wants them to come and talk to me about playing in competition and controlling their nerves and staying calm. I think it's both better education on the mental side at an earlier age in addition to the experience of earlier competition. Someone like Chip Beck will take a lot longer. But it's a good point.
Players can still do a routine.
If they're halfway through their routine by the time it's their turn to hit, it's only going to take them another 15 seconds to finish. It doesn't have to be a thing where you wait until the other person has played their shot, then you start your routine. What we know about learning and performance is that if you have an hour you're going to spend practicing, your time would be better spent on maybe spending fifteen minutes on each part of the game rather than spending an hour on the long game or an hour on putting, for example. It leads to better retention and better performance. One of the drills you mention is the 'success drill' where a student tries to sink twenty putts in a row from two feet, then twenty from three feet.
