How can I avoid swapping a participant's score with the opponent's score in research?
Choose the subject first, then label each score from that subject’s perspective: own score and opponent score. Keep the event, source, metric and orientation beside the numbers. If you later change which participant is the subject, recalculate the labels rather than copying the old own/opponent columns unchanged.

Anchor the ledger to one named subject
Score pairs are easy to reverse when notes move between participants, teams or events. Start each row with the subject and the event identifier. Then label which value belongs to that subject and which belongs to the opponent in that same event.
A source may display a home score first, list teams in a particular order, or use sport-specific set totals. Do not assume the first number is the subject’s score. Read the labels in the primary event record and preserve the metric exactly as published.
Keep own and opponent measures separate
A recent own-score average should use the subject’s own recorded score or set total from each included appearance. An opponent’s total is a different series. If the question is about an opponent conceding a score in its own latest appearance, keep that event and perspective distinct too.
Before calculating an average, confirm the same subject perspective, metric and inclusion rule for every row. Mixing a participant’s own totals with opponent totals can produce a number that looks precise but answers no consistent question.
Re-label the row when the subject changes
The same event can be described from either side’s perspective. If you switch the subject to the opponent, that event’s own and opponent values swap roles even though the source score does not change. Store the original source labels so you can rebuild each subject-specific view correctly.
Use a simple audit before sharing a comparison: read the subject name, event, own value, opponent value and source together. If any label is missing, do not guess the orientation from the score pair alone.
Hypothetical: the same score pair from two viewpoints
In a fictional ledger for one event, Team North is the named subject and the source records North at 2 and South at 1. The North-oriented row is own score 2, opponent score 1. If the subject changes to South, the same source pair becomes own score 1, opponent score 2. No score changes; only the subject perspective changes. These teaching values are hypothetical and are not an actual event or result.

Is the first score in a source always the participant’s score?
No. Source ordering may follow team, home/away or sport-specific conventions. Use the published labels and the named subject to assign each value.
Can I use opponent scores in an own-score average?
Not if the measure is the subject’s own score. Keep own and opponent values in separate series and state the metric being averaged.
