Bernard, you are being obtuse.
If I ask you how much gas my airplane consumes, when parked on the 
ground,  neglecting evaporation and thermal expansivity,
can you tell me the answer, to six decimal places?

If I share with you that the two fuel gauges on this aicraft each have 
scale lengths of 2 inches or so, and can be assumed
to be carefully calibrated near the empty mark, so that they are 
accurate to +_ 3%, like most other analog pointer moving scale meters 
are nearer full scale, could you reflect his experimental proviso into 
your graphs?
