Editorial policy
How this research is published
Scope and review status
We publish evidence reviews, verified extracts and practical research guides about tennis development. Each asset states whether it is original analysis, an editorial synthesis or externally peer reviewed. We do not present editorial work as peer-reviewed scholarship.
Sourcing
Preference is given to peer-reviewed papers, official tour or federation records, institutional repositories and current first-party prices. Every quantitative claim should identify the population, denominator or unit, time period and source.
Data and licence
Stakhovsky Tennis-created tables and extracts are released under CC BY 4.0 unless an asset says otherwise. Underlying third-party publications retain their original rights.
Corrections
Material corrections are dated in the asset changelog without erasing the prior version. Send reproducible corrections to leo@stakhovskytennis.com.
