Austin kickstarted the penultimate triple-header with a stunning victory for Kimi, but the works continues as F1 heads to the Autódromo Hermanos Rodríguez for the Mexico City GP.
"Austin demonstrated the potential we have with our latest update, but it also highlighted where we still have work to do," says Toto.
"We have added performance, but accessing it consistently is proving more challenging. George suffered particularly with that last weekend and, as a team, our focus is on understanding why and helping get the car into a better window.
"The championships are moving closer, but our mindset does not change. Thinking about the outcome won’t help us achieve it.
"We will stay disciplined, take each session as it comes, and concentrate on doing the fundamentals well. That includes Fred, who will take over George’s car for FP1. He is an important member of our team and we know we can rely on him to deliver precise, useful feedback as we work through Friday’s programme."
