Toto Wolff is adamant Mercedes will get the correlation "nailed on" with the W13 after a difficult start to the season.
The Silver Arrows have been up to a second off the pace of Ferrari and Red Bull in the opening three races of the year, with simulations and on-track performance varying due to the porpoising phenomenon.
Despite the struggles, Lewis Hamilton and George Russell have scored a podium apiece and the team sits second in the constructors' standings, 10-points clear of Red Bull in third.
Asked if he was losing faith with the data correlation given the team has historically been accurate with its simulations, Wolff insisted: "I believe that we are going to get it nailed on with this car as well.
"You can see that many other teams, like Ferrari, still have some bouncing but they have done many other things right that we have missed out on or we didn't perform very well, the same for Red Bull.
"Their car got quick from one day to the other in Bahrain testing by bringing the updates so this car is very difficult to correlate because you can only move the car with a certain frequency in the wind tunnel where it is limited and then on track it does something completely different."
Explaining Mercedes has what is needed to get on top of its issues, Wolff added: "This is a new way of analysing aero data, it is a new way of correlation between the simulations and the real world which needs to be understood.
"But we have the tools and people to understand that but we haven't found that yet."
