   HC differentials [AGS Max Score Per Hole: 8]

      2025 round 20, 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 18, full-18, score=95, AGS=94; HC differential = ((AGS-course_rating)*113)/course_slope = ((94-70.2)*113)/124=21.7 (rounded to nearest tenth)

      2025 round 17, full-18, score=99, AGS=99; HC differential = ((AGS-course_rating)*113)/course_slope = ((99-70.2)*113)/124=26.2 (rounded to nearest tenth)

      2025 round 16, full-18, score=91, AGS=91; HC differential = ((AGS-course_rating)*113)/course_slope = ((91-70.2)*113)/124=19 (rounded to nearest tenth)

      2025 round 14, full-18, score=98, AGS=98; HC differential = ((AGS-course_rating)*113)/course_slope = ((98-70.2)*113)/124=25.3 (rounded to nearest tenth)

      2025 round 3, full-18, score=95, AGS=95; HC differential = ((AGS-course_rating)*113)/course_slope = ((95-70.2)*113)/124=22.6 (rounded to nearest tenth)

      2025 round 2, full-18, score=93, AGS=92; HC differential = ((AGS-course_rating)*113)/course_slope = ((92-70.2)*113)/124=19.9 (rounded to nearest tenth)

      2025 round 1, full-18, score=96, AGS=95; HC differential = ((AGS-course_rating)*113)/course_slope = ((95-70.2)*113)/124=22.6 (rounded to nearest tenth)

      2024 round 19, front-9, score=48, AGS=48; HC differential = ((AGS-course_rating)*113)/course_slope = ((48-35.2)*113)/121=24 (2*12 for 18 holes, rounded to nearest tenth)

      2024 round 18, 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)

   player HC differentials sorted (10): 18.4, 19, 19.9, 21.7, 22.6, 22.6, 24, 25.3, 26.2, 27.2

   Total HC differentials: 10, # to use: 6 (lowest): 18.4, 19, 19.9, 21.7, 22.6, 22.6

   HC index = (average of 6 HC diffs)*0.96 = (124.2/6)*0.96 = 19.8 (removed digits after tenths)
