This forum contains threads to discuss teams themselves. Anything not technical about the cars, including restructuring, performances etc belongs here.
They may be trying to compare the behaviour of the car vs today's, to better understand the front ends quirks. They might be able to use different setup ranges to see what this does to the behaviour of the car and compare it to the 39, to help inform what they want to do to make it more precictable at peak speeds on Saturday. And I guess that would stand for any area of the car.
Something interesting about the 2023 car is that it was an absolute beast in high speed corners after the Austria GP update, but it was really bad on medium-speed and long-radius corners so any gains they made in high speed sections they tended to lose it back on mixed tracks. Singapore package made the 2023 car more balanced and that sort of philosophy carried over into 2024. They "sacrificed" their strength to make an overall more balanced car.
A cool comparison point is T4 in Hungaroring. In 2023, Lando smoked the field there and even RedBull was completely outclassed. The 2023 car was so good there, that the MCL38 the next year was also no better than it (although not by much, loses around 0.02s).
