Each row represents a unique bout identified by MatchLink-href. The table contains 24 matches with complete fight statistics for both boxers. While web-scraper-order appears sequential (monotonicity 0.522 for f_boxer_age suggests chronological scraping), the primary organization is by match identity, not temporal progression. The classifier correctly identified this as dimension type despite some event-like characteristics (the matches are discrete occurrences, hence the event=0.30 tag), but the table's purpose is reference/lookup rather than event stream analysis." } ] } ```
