However, the question asks about duplicate or near-duplicate ROWS, not just duplicate IDs. I need to check if there are rows that share the same combination of key attributes (task, model, task version) which would indicate the same benchmark run recorded multiple times, or rows with identical scores/results that might be near-duplicates. Let me check for rows with identical combinations of the main dimensions.",
