Updated 4-Test Series Outcome Projection (South Africa Leads 2–1)

🇿🇦 Projected Outcome: Springboks 3–1 Series Victory (55.4% Probability)

10,000 Monte Carlo Runs: 🇿🇦 Springboks 3–1 Win 55.4% | 🤝 2–2 Series Tie 41.8% | 🇿🇦 SA 2–1 (Draw) 2.8%

💡 Why is South Africa (55.4%) Favored to Win the Series 3–1?

South Africa Leads 2–1: Following back-to-back victories in Cape Town (33–26) and Johannesburg (29–24), the Springboks hold the series lead heading into the USA finale.
Only Test 4 Remains: South Africa only needs a win or draw in Test 4 to claim the series outright (3–1 or 2–1).
All Blacks Win-or-Bust: New Zealand must win Test 4 on neutral American turf to salvage a 2–2 series draw (41.8% probability).
