This part is quite interesting to me:
"The construction of mathematical models that help to be predictive of reality, indicating possible lines of development, becomes fundamental."
Prediction with mathematical modeling is theoretically possible but very hard to achieve in reality.
It is rock and a hard place to model/predict variables that has impact on the model, that is the key in mathematical prediction.
That means to forecast errors i.e. variations of the environment, predictions of quality and quantity of variations that will have impact on the model, BUT they still doesn't happen. The only source is to model them on historical data and that data has variations in the history and also interactions between different variables must be estimated and of the top of that impact of these exogens on the endogen i.e. the car for which you have data but it is also a complex system.
The crucial part of the model is the exogen which means to model something that never occurred.
I am very interested what and how they do in the process of mathematical modeling.
Obviously RB find something that is functioning real well or better to say useful.

You can always improve the mathematical models, simplest thing is to introduce new variables. You can also establish new and improved "fit" functions for all parameters. This is especially important in car dynamics models, I imagine. The better the input, the better the output. With more input and complex calculations required, the more computing power you need, so you also need to improve that from time to time.
CFD simulations are complex as they are and you can make a lot of improvements by improving the selection of car attitudes that you simulate, more or less yaw angles, more or less roll angles, steering angles, tyre deformation, bodywork deformation, etc. This is just the basic stuff... With the introduction of teraflop limits (it feels it's been ages already
) it became very important to optimise the calculations and make sure you can make them as fast as possible. With less and less reliance on wind tunnel and almost non-existent track testing, CFD is ever more important, closely followed by car simulator. Also, your turbulence models need correction every few months to fit the latest track-information. These are not big changes, but everything counts...
All of this and much more is where RB is ahead. They entered F1 when testing, WT and CFD limits have just begun, so it's logical to assume they put more focus on computation tools right away. I heard they hired some people from simulation software companies to help them improve in this area as soon as they entered F1, not sure if they keep feeding personnel from those companies on a regular basis.
