Calculate hit factor or infer elapsed time from recorded stage scores, with optional stage-winner comparison.
Hit Factor Formula
Net points = max(0, gross points − penalties); hit factor = net points / elapsed seconds
Calculate the Recorded Score
Hit factor expresses net scoring points per second. Choose the recorded scoring category and enter A, C, and D hit counts. The standard values used here are 5, 3, and 1 points for Minor, or 5, 4, and 2 for Major. Enter assessed miss, no-shoot, and procedural penalty counts. This calculator subtracts 10 points for each entered penalty and floors the net score at zero.
Choose Hit Factor or Elapsed Time
To calculate hit factor, enter elapsed stage time in seconds. To infer elapsed time, enter a positive recorded hit factor. The reverse formula is elapsed seconds = net points ÷ hit factor. A positive factor with zero net points cannot produce a valid positive time and is rejected. A zero net score with a valid positive time produces a hit factor of zero.
Worked Example
With 12 A hits and 4 C hits in Minor scoring, gross points are 12 × 5 + 4 × 3 = 72. With no penalties and a time of 18.5 seconds, hit factor is 72 ÷ 18.5 = 3.8919 points per second when rounded to four decimals. Adding one assessed 10-point penalty changes net points to 62 and the result to 3.3514.
Optional Stage-Winner Comparison
Open Assessed penalties and stage comparison to enter the winner’s recorded hit factor and maximum available stage points; enter both or neither. The comparison must use the same stage and division. Stage percentage is your displayed four-decimal hit factor divided by the entered winner hit factor, multiplied by 100. Proportional stage points use the same fraction times maximum available points. For example, 4.0000 compared with 5.0000 is 80%, giving 80 points on a 100-point stage.
Check What the Inputs Represent
Hit counts and assessed penalty counts must be whole, nonnegative numbers. Enter zero for unused required hit counts; blank optional penalty counts mean zero. The scoring category is the category already assigned to the score; the calculator does not determine equipment eligibility. The stage winner comparison rejects a reference lower than your displayed factor and a stage maximum lower than your gross score.
Rounding and Comparability
The main hit factor display uses four decimal places. A time reconstructed from a rounded recorded factor may differ slightly from the original timer reading. Do not treat hit factors from unrelated stages as a direct ranking: stage design and available points differ. A stage percentage is also different from a classifier percentage, which requires the relevant classifier reference and classification rules.
Scope and Limitations
This is a standard point-tally and rate calculator. The official score sheet, written stage briefing, assessed penalties, and governing scoring system take precedence. Special penalties or scoring methods that do not use the displayed 10-point deductions and points-per-second relationship are outside this tally. The optional comparison does not combine multiple stages or issue an official classification. Calculate saves the inputs and successful result locally; Reset clears that saved state.
Reference Table
| Scoring item | Minor points | Major points |
|---|---|---|
| A hit | 5 | 5 |
| C hit | 3 | 4 |
| D hit | 1 | 2 |
| Each entered penalty | −10 | −10 |
