Data source and methodology
NPB Magic Number turns the NPB Central and Pacific League standings race into numbers you can act on: Climax Series odds, magic numbers by place, head-to-head records, and a dedicated page for every club.
Standings and head-to-head records come from npb.jp's official, freely published standings tables - basic stats only (wins, losses, ties, winning percentage, games back), nothing from NPB's paid NPB BIP data business. Results are cached for 30 minutes to limit load on npb.jp, and every page shows its as-of time. In the off-season this shows the prior season's final standings and switches to live data automatically once the new season starts.
This site doesn't use club logos, emblems, or player photos - just team colors and short names. The standings table is also its own design, not a copy of npb.jp's layout.
This is an unofficial, fan-made site with no affiliation to NPB or any club, and its analysis is for reference only. For official standings and records, check npb.jp. Let us know if you spot an error.
