Reference consumption decreases and increases depending on speed

Calculation of the reference consumption linked automatically by data from my car (Tesla Y LR) change a lot if driving slow or fast. The reference consumption should be what you write a theoretically consumption at 110km/h on a horizontal road with no wind and no rain. It should not increase if you drive fast for some time. It should not decrease if you drive slow for some time. Your calculation is not correct due to the fact that the reference consumption change a lot - more than 25%. The only way I can use ABRP is not to use the automatically linked reference consumption as it is wrong. Please have your math revised.
