   HC differentials [AGS Max Score Per Hole: 8]

      2026 round 9, full-18, score=99, AGS=99; HC differential = ((AGS-course_rating)*113)/course_slope = ((99-69.6)*113)/125=26.6 (rounded to nearest tenth)

      2026 round 8, full-18, score=104, AGS=102; HC differential = ((AGS-course_rating)*113)/course_slope = ((102-69.6)*113)/125=29.3 (rounded to nearest tenth)

      2026 round 5, full-18, score=102, AGS=102; HC differential = ((AGS-course_rating)*113)/course_slope = ((102-69.6)*113)/125=29.3 (rounded to nearest tenth)

      2026 round 4, full-18, score=97, AGS=97; HC differential = ((AGS-course_rating)*113)/course_slope = ((97-69.6)*113)/125=24.8 (rounded to nearest tenth)

      2026 round 3, full-18, score=105, AGS=104; HC differential = ((AGS-course_rating)*113)/course_slope = ((104-69.6)*113)/125=31.1 (rounded to nearest tenth)

      2025 round 20, full-18, score=100, AGS=100; HC differential = ((AGS-course_rating)*113)/course_slope = ((100-69.6)*113)/125=27.5 (rounded to nearest tenth)
