The tight clustering of implied probabilities around 48-50% for drivers including Yuki Tsunoda, Carlos Sainz, Lando Norris, and several midfield runners stems primarily from the unpredictable nature of FP1 on Baku's demanding street circuit. Teams routinely prioritize data collection, varied tire compounds, and setup experiments over outright single-lap pace in the opening session, producing scattered times that rarely reflect true qualifying or race form. With sunny conditions and temperatures near 27°C forecast, track evolution and minor incidents common on the walls-lined layout further flatten expectations across the field. Recent championship momentum for frontrunners like Kimi Antonelli and McLaren offers limited guidance for this early session, keeping trader consensus evenly distributed until more representative running occurs.
