pistelaskun

Pistelasku (genitive: pistelaskun) is a Finnish term referring to the calculation and tabulation of points used to rank or evaluate performance in games, sports, competitions, tests and other scoring systems. It covers both the mathematical procedures that convert actions or outcomes into numerical scores and the rules that determine how those scores are aggregated, weighted and compared.

Common contexts include team and individual sports (league tables, tournament standings), judged competitions (gymnastics, diving), academic grading and entrance examinations, loyalty or reward programmes, and competitive events where points determine advancement or prizes. Methods vary from simple summation of points to weighted scores, averages, normalized indices, penalty deductions and bonus adjustments. Tie-breaking procedures such as head-to-head results, goal difference or additional playoffs are often integral parts of pistelaskun.

Design considerations emphasize fairness, transparency, robustness against manipulation and ease of calculation. In modern practice pistelaskun may be implemented with software that automates tallying, applies scoring algorithms and produces real-time leaderboards. Rulesets and governing bodies typically codify the precise pistelaskun to ensure consistent application across events and seasons. The term should not be confused with lasku in the sense of an invoice; in everyday Finnish usage pistelasku specifically denotes point scoring.
