For the return of ground effect in 2022, Mercedes sought to run the W13 as low to the asphalt as possible to achieve maximum theoretical downforce.
But the car was hurt by severe porpoising as the surface bumps and imperfections forced ride height concessions that meant the team could not replicate its wind tunnel simulations achieved in perfect control conditions.
However, a sprint and grand prix victory for George Russell in Brazil late last year encouraged Mercedes to stick with its unique size-zero sidepod car architecture over the winter.
But for 2023, it is believed that the team moved too far the other way to design its W14 challenger around an overly high ride height.
Having then been able to lower the set-up, the team then struggled to consistently keep the machine within its ideal operating window.
As the engineers sought to optimise the car during each weekend, this led to large swings in performance.
Often Russell and team-mate Lewis Hamilton were slower in the early practice sessions, could relay contrasting feedback over car handling and would significantly change the set-up heading into FP2.
Then the pair would begin to progress in qualifying and finally hit their peak performance in the later stints of the race.
The overnight turnarounds have often been credited to the remote simulator work being carried out by third driver Mick Schumacher.
Team boss Toto Wolff sought to explain the trend earlier this season, saying: "We tend to make a jump from Friday to Saturday in understanding in the overnight simulation work. And you can see that on the sprint weekends, we struggle more than a conventional weekend."
