Reproduce one completed 18-hole WHS Score Differential from exact score, rating and PCC records and compare an independent same-round value.
A quick decision brief for this specific tool
One de-identified completed 18-hole record and basis; named completed adjusted-gross-score, exact course/tee Course Rating and Slope Rating, recorded PCC and independent Score Differential sources; plus the copied numeric score, ratings, PCC and independent differential
Preserved one-round provenance, score-minus-rating-and-PCC term, unrounded and nearest-tenth reproduced Score Differential, independent differential and signed reproduced-minus-independent difference
Apply the current one-round formula (113 ÷ Slope Rating) × (adjusted gross score − Course Rating − PCC), round to the nearest tenth with .5 upward, and compare the same-round independent record; do not average multiple rounds or apply the obsolete 0.96 multiplier
Choose your path
Reproduce one completed 18-hole Score Differential from exact source-owned score, rating and PCC records and compare an independent same-round value without issuing a Handicap Index or posting verdict.
Check one copied Score Differential without applying an obsolete multiplier or reusing another tee's ratings.
Name the completed round and exact tee/PCC sources, copy the adjusted gross score and rating values, then compare the reproduced tenth with the independent record.
Can see the size and direction of a one-round discrepancy while official posting and Handicap Index remain with the authorized system.
Explain which arithmetic belongs to a Score Differential and which safeguards belong to an official Handicap Index.
Load the 85/72/130/PCC-0 exercise, inspect all four steps, then change PCC or the independent tenth to demonstrate the record boundary.
Does not confuse a one-round differential, best-8 average, Low Handicap Index caps, exceptional-score reduction or Course Handicap.
Show why each completed round owns its own adjusted score, course/tee ratings and PCC instead of sharing one pair across a score list.
Retain de-identified provenance for one round, trigger a Slope/PCC validation error, recover with source-backed values, save deliberately and export the calculation boundary.
Learners can reproduce the current formula and route score acceptability, posting and official-index questions to the proper process.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Tools you might need next
Reconcile 1–18 completed regular stroke-play hole scores with matching pars. Reproduce gross total and score to par without certifying or posting a score.
Reconcile 3–20 carry observations from one completed, source-labelled golf-club session. Reproduce mean and range without predicting distance or club choice.
Reconcile 1–18 completed, source-classified GIR or MISS hole records. Reproduce count and percentage without inventing benchmarks, causes or advice.
Each input must belong to the same completed 18-hole course-and-tee record. This worksheet does not determine whether the score is acceptable, fill unplayed holes, create an expected score or reuse one rating pair across unrelated rounds.
One round = one adjusted score + exact Course Rating/Slope Rating + recorded PCCUse the exact recorded PCC from −1 through +3 and matching Slope Rating from 55 through 155. Round the result to the nearest tenth with .5 upward, as specified for the one-round calculation.
Score Differential = (113 ÷ Slope) × (Adjusted gross score − Course Rating − PCC)The signed difference is a record-review flag only. An official Handicap Index uses an authorized scoring record and can include exceptional-score or Committee adjustments, Low Handicap Index and caps. The obsolete 0.96 multiplier is not used.
Difference = Reproduced differential − Independent differentialUpdated: August 2026
A completed round has adjusted gross score 85, exact Course Rating 72.0, Slope 130 and PCC 0. The worksheet reproduces 11.3 and agrees with an independent 11.3 record without calling it a Handicap Index.
The copied round originally omitted a recorded PCC of +1. Reproducing the exact source basis changes the differential to 10.4 and exposes the mismatch for the scoring-record owner to resolve.
A reviewer discovers that the independent value uses another tee's ratings. The sources are corrected before comparing; the worksheet never treats a plausible number as evidence that the records match.
Use this retrospective worksheet for one already completed, source-labelled 18-hole round. Copy its already determined adjusted gross score, exact course-and-tee Course Rating and Slope Rating, recorded PCC adjustment and an independent same-round Score Differential. The page reproduces the current one-round arithmetic; it does not issue a Handicap Index or post a score.
