Excel workbook
All three tables in one .xlsx file, as separate worksheets: championship records, every epicenter range, and the locality audit. Generated from the same bytes as the CSVs above.
Download Excel workbookRead the coordinate method: every counted row uses a verified, season-specific home-stadium coordinate. Defunct 1920s grounds carry documented historical-site coordinates with explicitly lower precision — visible in the CSV rather than hidden.
Coverage: Champion coverage spans the APFA/NFL founding in 1920 through the latest completed season. AFL champions 1960-1969 are recorded as a separate non-counted layer. Defunct-franchise grounds from the 1920s use documented historical-site coordinates flagged with lower precision in the public CSV. A source link identifies the evidence used for the cited field; it is not an endorsement of every statement on the linked page.

Reading the table
- Counted means the claim contributes to the epicenter under the current policy: NFL/APFA champions 1920-1965 and Super Bowl winners from 1966.
- Recorded, not counted preserves the ten AFL championships (1960-1969) without giving them geographic weight. The 1968 Jets and 1969 Chiefs appear in both layers — one championship season seen from two league perspectives, counted once.
- Notes flag seasons with venue subtleties, like the Cowboys' 1971 mid-season move into Texas Stadium.
