Mercedes Team Principal Toto Wolff has insisted he will not rely on simulations to conjure expectations for the Las Vegas Grand Prix weekend.
The Brackley-based squad enters the race weekend having suffered a troubled event last time out in Sao Paulo.
Both Lewis Hamilton and George Russell endured high tyre degradation during the race with Hamilton scoring eighth while his team-mate was forced to retire late in the Grand Prix.
Wolff described the weekend as Mercedes' worst since it rejoined the grid as a manufacturer in 2010.
Next on the schedule is the long-await trip to Las Vegas, which will be a step into the unknown for the teams due to the track being a new addition to the calendar.
Wolff has asserted that he is not forming any pre-event goals based on simulator data after its torturous weekend in Brazil.

An enormous effort
“I'm not sure, I will not rely on the simulations at the moment,” he told media including RacingNews365.com.
“There's an enormous effort that Liberty undertook with Las Vegas and I think it's going to be a tremendous show for the audiences, for us.
“I don't know what to expect. You can see those swings you asked me [in Mexico] and I'm like, 'yeah, we're going to Brazil and this is going to be awesome'.
“Now we're going to a track that we haven't been in even, so I don't know.”
