There was a guy on here that damaged the fuel sensor crossing the desert and the gauge was showing low even when there was essentially half a tank left. I'm sure he said it kept going into limp mode basically after a few hundred kilometres and then cutting out. This would mean you couldn't run with zero kms on the range read out because the computer would stop the car. Is this the case or am I misunderstanding or remembering wrong?

± 0.3% for fuel.

We probably have the same fuel tolerances at you. With a 68 litre fill you could be getting a maximum under or over error of 0.204 litre.

It would not surprise me at all if fuel pumps have been calibrated close to the minimum tolerance.

Many years ago I was in an industry which sold finished products by weight. Then changed to selling by piece. I found out from the old to the new system over about a year when everything had been changed. Products weighed about 7% less, but everything was still within the Standards. Yes, just within the minimum standard. Before everything was just under the maximum standard.

Standards and tolerances are easy to meet, so products are going to be sold close to the minimum or maximum standard. Whichever end of the spectrum suits the seller.

My personal opinion is when you are paying for 68 litres of fuel, you are probably getting about 67.83 litres because the pumps should easily be accurate enough to have them dispense fuel at the lower end of the tolerance but still have a safety margin. So probably about -0.25% at a guess for the average pump. Procrastination, mankind's greatest labour saving device!
