How often does the team that tops testing win the title?

As the F1 season approaches, the long-standing question of whether pre-season testing dominance translates into a Constructors' Championship win has been revisited. F1's data analysts have delved into historical data, unearthing intriguing conclusions. While testing provides the crucial first opportunity for teams to iron out kinks in their new cars, predicting the true competitive landscape from lap times alone is notoriously difficult. Observers cannot discern fuel loads, engine modes, or specific run plans, making a definitive assessment before the season's start a challenging endeavor. The real pecking order often only emerges under race conditions.
