George Russell's commanding 1m45.387s lap in FP1 at Baku City Circuit underpins the overwhelming 99.5% implied probability for the Mercedes driver to claim the session's fastest time. Russell benefited from a well-timed tow along the long straight and delivered his benchmark midway through the disrupted hour, finishing 0.400s clear of Max Verstappen while outpacing Ferrari's Charles Leclerc and Lewis Hamilton. Compounding factors included Kimi Antonelli's early hydraulic failure that limited his running, McLaren's garage time for both cars, and limited soft-tire attempts from rivals. With the session complete and timesheets confirming the order, only a post-session timing correction or data review could realistically shift the outcome.
