I took my son to a US Kids parent-child golf camp a few years back. Before giving us an afternoon to play the course, they gave us a quick talk on their system and had us all go to the range and hit a few drives to figure out the best tees to play from. It seemed to work pretty well, although I’m conservative, was sort of between tees, and chose to “round down” instead of playing the longer tees. Pro caught up to us about halfway through the first nine, watched me play a couple holes, and suggested I think about moving back a tee as he drove off.
