The old adage that you're only as good as your last race applies as equally in Formula 1 as anywhere else, but the capacity to get away with the odd lemon is greatly reduced by the microscopic scrutiny modern grand prix drivers are exposed to.
The very best deliver top-notch performances almost week-in, week-out, with hardly any notable mistakes. For Lewis Hamilton, Sebastian Vettel, Fernando Alonso, Max Verstappen, or Daniel Ricciardo, a below-par F1 weekend is a real anomaly.
Valtteri Bottas, Carlos Sainz Jr, Sergio Perez, Esteban Ocon and Nico Hulkenberg are often top-notch too. The likes of Pascal Wehrlein, Romain Grosjean and Kevin Magnussen haven't quite hit the same peaks as consistently so far, but nevertheless have no real reason to feel concerned.
