    "content": "**No duplicate rows were found in this dataset.**\n\nI checked for exact duplicates across all key identifying columns (Rank, Previous, ID, Assoc, Gender, Name, Points, Previous Points, WeekNum, MonthNum, YearNum) in both tables, and the query returned zero rows with duplicate_count > 1.\n\nThis means:\n- Each ranking entry appears only once for its specific combination of player, rank, points, and time period\n- There are no exact row-level duplicates in either the men's rankings (raw.ittf_rankings) or women's rankings (raw.ittf_rankings_women) tables\n\n**Regarding near-duplicates:** The dataset structure suggests near-duplicates would be unlikely to be problematic here. This is a time-series ranking dataset where:\n- Players naturally appear multiple times across different weeks/months/years as their rankings evolve\n- The same player at the same rank in consecutive weeks would have different Points values if their performance changed\n- The temporal columns (WeekNum, MonthNum, YearNum) ensure that legitimate repeated measurements are distinguished\n\nThe absence of exact duplicates indicates clean data ingestion with no accidental row repetition during the ETL process."
