Inspect one yard/meter at a time and assign points based on defect severity: 1 point for minor defects (≤ 3 inches), 2 points for medium (3-6 inches), 3 points for larger (6-9 inches), and 4 points for major defects (> 9 inches). Total the points and ensure they don't exceed the pre-established acceptance level for quality control.
