Can every player statistic be converted into an opponent allowed statistic?
No. A participant's own recorded statistic does not automatically provide the amount an opponent allowed or conceded. Use an allowed version only when a source directly defines a comparable metric for that opponent. Keep its season, sample, unit, and cutoff explicit. If the counterpart is not defined or cannot be verified, say it is unavailable; do not invent an equivalent by reversing a value or subtracting from a total.

A participant's output and an opponent's allowed value differ
An own-performance statistic records what a participant produced under a defined metric. An allowed or conceded statistic describes a different perspective and may use a separate source definition. Similar names do not prove that the measures are reciprocal or interchangeable.
- Check that the source labels the statistic as allowed or conceded.
- Match the event type, unit, season, sample, and cutoff.
- If no direct counterpart exists, report that it is unavailable.
Do not manufacture a defensive measure
Subtracting a participant's value from a team total or changing the subject label may not produce a valid opponent-allowed statistic. Without a documented formula and matching source data, that calculation answers a different question. Keep the directly observed statistic and the missing counterpart distinct.
Report the period and denominator with the measure
If an allowed metric is available, state the season identifier, completed-appearance sample, measurement unit, and research cutoff. A season average and a last-10 average are different windows; do not combine them or describe one as the other.
Hypothetical example: leave a missing counterpart unavailable
Imagine a fictional ledger with an own-performance row showing 8 generic units per appearance over 12 completed appearances in season S-HYP. A second row for an opponent-allowed version has no directly defined source field or sample. Report the first row with its own scope and mark the counterpart unavailable; do not relabel the 8-unit average or subtract it from an unrelated total. Every label and value here is synthetic, not real sports data.

Can I subtract a player's average from a team total to get an allowed average?
Not without a documented definition and compatible data. Otherwise the subtraction may represent a different measure, so leave the allowed statistic unavailable.
