Perhaps Ferrari has measured it correctly, but in a different way from the previous times,
which could have created a difference in the end result,
which does not match the measurement of the FIA that has always done it in the same way .
If you do not state that you have measured it differently, you will be fined. Maybe that fine was for that?
Just an idea, because it will always remain a mystery.
There is clear communication to the teams of how the fuel will be measured when this new Technical directive was given in February (the article below mentions this method, which was given out in February 2019)
https://www.motorsport.com/f1/news/fia- ... s/4339766/
Teams will now be asked to declare how much fuel they are planning to put in the car for the race, and FIA technical boss Jo Bauer and his team will have the right to weigh the cars before and after the race in order to determine exactly how much fuel has been used – and how that matches up with what has been recorded by the fuel-flow meter.
The strict new procedures were outlined in a technical directive from FIA head of single seater matters Nikolas Tombazis that was circulated to all teams last Tuesday.
Henceforth teams have to declare the amount of fuel they intend to put in the car – which covers the laps to the grid, the formation lap, the race and the in-lap – at least two hours before the race start.
This amount of fuel has be in the car's tank no later than one hour before the pitlane opens, after which time no fuel chilling will be allowed.
The FIA then reserves the right to randomly check cars before the race, with the car weighed with a set of "travel wheels" marked by the FIA and with a known weight.
The team will then be asked to drain the fuel tank, with the fuel pump then run to ensure that all remaining fuel goes into the collector – and the FIA will then make sure that there is nothing left in the car.
The car will then be weighed again, and a fuel mass calculated from the difference with the earlier weight. The fuel will then be pumped back into the car, which will then be weighed for a third time, after which point the fuel hatch and QD (quick disconnect) will be sealed so no fuel can be added or removed.
Following the race the FIA can again choose cars for random fuel checks, after the usual parc ferme procedures have been carried out. The car will be weighed with the same marked travel wheels used in previous checks.
As before the team will be asked to pump out any remaining fuel, and the FIA will make sure that none remains in the car. A further weight check will be used to determine that mass of fuel that has actually been used from the laps to the grid to the in-lap. The car will be then be weighed again.
Tombazis notes that "The difference between the pre- and post-race fuel masses will be assumed to be the measured fuel mass used (which clearly includes laps to the grid, formation laps, fire-ups etc.).
"It can be compared to the integrated FFM [fuel flow meter] figures and to the fuel injectors model figures in order to provide confirmation of the validity of these readings.
"Please note that the pre-race fuel mass that gets used for this calculation is either the declared mass, or the measured mass if this has been randomly checked."
Dont tell me that Ferrari are now incompetent to understand the method the FIA uses, which has been given out in February 10 months ago.
Also Tombazis gives out furthur warnings
Tombazis has also given a very specific list of situations which may trigger further investigations, and/or the team concerned being reported to the stewards. It reads as follows:
1. If the fuel pump-out procedure differs from the declared and documented process that the team is required to communicate to the FIA in advance.
So any process difference a team has done should have communicated to the FIA! So there is no chance to have different methods for each team, they should follow the same procedure
