Why can a full-event statistic not answer a question about one declared period?
A full-event statistic combines activity across the event, while a declared-period statistic covers only the named segment. The total cannot reveal how much occurred in one period without the period-level record. State the period definition, metric, unit, event, and sample window; do not substitute a full-game total for an opening-period value or average. Historical period frequencies and averages also describe only the specified records, not a future event.

A period is not the whole event
A period may be defined as a half, quarter, inning, set, or another sport-specific segment. Its boundaries come from the event format and source. A full-event total may combine multiple segments and cannot be split accurately without the underlying period values.
- Name the exact period and its boundaries.
- Use the same metric and unit for the period and full-event records.
- Keep the event and appearance window attached to each value.
Period values, averages, and condition counts are distinct
One event's period value, an average across several events, and the frequency of a condition are different summaries. Each needs its own denominator and declared period. Do not derive an opening-period number by subtracting another event total unless a documented source definition supports that calculation.
Do not use a full-event total as a period result
When a period-specific source is missing, report that it is missing. A full-event total may provide broader context, but it does not answer what happened in a particular period or whether a period-specific condition was met.
Hypothetical example: one period and full event have different values
Suppose a synthetic event record shows 12 generic score units in the declared opening period and 57 units for the full event. The period value is 12; the full-event total is 57. The total alone would not reveal the opening-period value, and neither number supplies the other 9 events needed for a last-10 average. These invented values do not describe a real event or selection.

Can I use the full-game total to calculate an opening-period average?
No. You need the opening-period values for the relevant events and the defined sample. Full-event totals do not identify the segment values.
