Choose the amount of gasoline that will not add the amount you want to achieve

Sorry, what?

I quite don't understand the sentence

Maybe he means he wants the old refuel system back? Where instead of specifying how much fuel gets added, you instead set up to what percentage your fuel tank will be filled up to.

Honestly, the old system was scrapped, and for a good reason, so: -1

Personally, I prefered the old system.

I just don't see the practical reason for it? What advantage did the old system have over the new one?

With the new one, if you have for example a one pit strategy and run with half the fuel needed for the race length both in the fuel tank and set up as amount to refuel, then you're completely safe to pit in a few laps earlier should the need arise (as long as the fuel tank can hold the combined amount). If you need to pit again then it's also quite easy to just set the refuel amount to 0%.

If you need to pit in earlier with the old system then you frantically have to recalculate the new, higher amount needed or you won't have enough fuel to complete the race.

It is more practical the old system, but not realistic

Not more practical either, as Android stated perfectly just above you

Not practical for you, but it was for me.

You calcule that in a long Race you will consume 120% of fuel, start race with 80% and calcule 40% for the second stint.

In the actual system you can put like that, but if you consume less fuel than you stimate you will finish the race with a lot of more fuel than you need. In the old system you will fit to 40% and you will finish the race with only a few more fuel than you need.

Please do not tell me how I think things through. And Believe that others do not think like you. Not winked

But that calculation is only correct in one(!) specific situation: When you pit exactly in the forsought lap ... an earlier pitstop will leave you without fuel, a later one with even more fuel ... Besides, what would be the maximum "fuel-overload", you'd carry that way? Say 2-3 % ... neglectable in my opinion ... but well ... if you thought it more practical before, do so, I can't see that ...

Then the problem is in your calculation not the system.

I don't see any problem with the system, only with avetere because he thinks he has the truth and that there can be a different

Now ... where did I say that?!
I only disagreed with your opinion, that the old system was more practical than the new one (for the reasons Android already gave). As this is just opinions and/or personal use/behaviour there obviously is not right or wrong, not even speaking of thruth ...
I can't remember me saying "Listen people, here comes the truth" nor something similar ...

I just cannot see, why - even with your example - the old system is more practical, since I regard the gain of the new one (more flexibility in general) more important than the loss (more "overfueling" in some occasions) ...

Not less but neither more ...

Actual system is easier. If you know that you'll need 40%, you only have to do this:

pit_fuel = 40 - (minus) initial_load

with the old system you have to count how many laps left to the scheduled stop.
It's the real way of making it, but more complex to adjust while racing
