## Do you have 20 scores on your golf handicap?

But lots of people don’t have that number on their record and this is where the fun and games start. Your handicap will continue to develop until it contains those 20 scores and the number of score differentials that are used to calculate it varies according to the number you’ve played.

Here’s a handy chart from the R&A and USGA that should hopefully help explain it a bit better. So, let’s say you have four scores in your record.
