Strokes Gained Off-the-Tee Calculator
Reconcile actual tee shot/penalty/leave evidence with caller expected-strokes benchmark before and after; no inferred shot-distance model or professional baseline.
Description
Tee-shot strokes gained compares benchmark expected strokes before and after actual shot/penalty costs.
Tee-shot strokes gained compares benchmark expected strokes before and after actual shot/penalty costs. The benchmark is caller supplied.1
The returned values include Strokes gained by tee shot, Total observed tee strokes gained. The How section below explains the calculation, input rules and interpretation.
When to use Strokes Gained Off-the-Tee Calculator
Use Strokes Gained Off-the-Tee Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No distance-based benchmark, professional baseline or shot-quality causation is inferred.
Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
How to use Strokes Gained Off-the-Tee Calculator and understand its results
- Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
- Enter callerExpectedStrokesBeforeTeeShots, callerExpectedStrokesAtObservedLeave, observedShotAndPenaltyStrokes using the field table and calculation rules, then run the tool.
- Read strokesGainedByTeeShot, totalObservedTeeStrokesGained. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| callerExpectedStrokesBeforeTeeShots | Caller expected strokes before tee shots | list of number | Required |
| callerExpectedStrokesAtObservedLeave | Caller expected strokes at observed leave | list of number | Required |
| observedShotAndPenaltyStrokes | Observed shot and penalty strokes | list of number | Required |
Enter aligned nonempty nonnegative expectations and integer shot-plus-penalty costs 1–20. Return signed shot gains and pooled total.
gain=beforeExpected−observedStrokes−leaveExpected Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| strokesGainedByTeeShot | Strokes gained by tee shot | list of number |
| totalObservedTeeStrokesGained | Total observed tee strokes gained | number |

}Limitations and assumptions
No distance-based benchmark, professional baseline or shot-quality causation is inferred.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Scrambling Up-and-Down Percent: Scrambling percentage is conditional on missed greens. Par-or-better recoveries are successes under this declared convention. For a complementary task, use Drive Carry/Roll Distance Split: Observed total drive distance minus carry gives signed roll. Negative roll can expose mismatched evidence and is preserved.
