   HC differentials [AGS Max Score Per Hole: 8]

      2025 round 8, full-18, score=89, AGS=89; HC differential = ((AGS-course_rating)*113)/course_slope = ((89-70.2)*113)/124=17.1 (rounded to nearest tenth)

      2025 round 7, full-18, score=97, AGS=97; HC differential = ((AGS-course_rating)*113)/course_slope = ((97-70.2)*113)/124=24.4 (rounded to nearest tenth)

      2025 round 6, full-18, score=100, AGS=100; HC differential = ((AGS-course_rating)*113)/course_slope = ((100-70.2)*113)/124=27.2 (rounded to nearest tenth)

      2025 round 5, full-18, score=93, AGS=93; HC differential = ((AGS-course_rating)*113)/course_slope = ((93-70.2)*113)/124=20.8 (rounded to nearest tenth)

      2025 round 2, full-18, score=100, AGS=100; HC differential = ((AGS-course_rating)*113)/course_slope = ((100-70.2)*113)/124=27.2 (rounded to nearest tenth)

      2025 round 1, full-18, score=103, AGS=103; HC differential = ((AGS-course_rating)*113)/course_slope = ((103-70.2)*113)/124=29.9 (rounded to nearest tenth)

      2024 round 19, front-9, score=47, AGS=47; HC differential = ((AGS-course_rating)*113)/course_slope = ((47-35.2)*113)/121=22 (2*11 for 18 holes, rounded to nearest tenth)

      2024 round 18, front-9, score=44, AGS=44; HC differential = ((AGS-course_rating)*113)/course_slope = ((44-35.2)*113)/121=16.4 (2*8.2 for 18 holes, rounded to nearest tenth)

      2024 round 15, front-9, score=45, AGS=45; HC differential = ((AGS-course_rating)*113)/course_slope = ((45-35.2)*113)/121=18.4 (2*9.2 for 18 holes, rounded to nearest tenth)

      2024 round 14, front-9, score=47, AGS=47; HC differential = ((AGS-course_rating)*113)/course_slope = ((47-35.2)*113)/121=22 (2*11 for 18 holes, rounded to nearest tenth)
