Scoring differential measures the gap between course rating and your score, averaged across your best 75% of rounds. That's different from handicap, which uses only your top 20% of scores. The wider sample gives a truer picture of how you actually play.
Here, scoring differential is just the difference between the course rating, whatever your child shot, right? Whatever that number is, if they're shooting better, that's negative, and it's going to be the average of the top 75%. Quick context here: when you look at handicap, that's the top 20— the average of the top 20%, right? So this is the top 75%. It's a little bit more representative of the player's scoring average. That's, that's really the most important metric that I like to look at.
