Manual correction of the reference consumption

Hello dear ABRP team, I was driving the Leipzig - Erfurt route and noticed that the calculated SoC in Erfurt was 15% different from the actual SoC. I therefore looked in the settings and noticed the following. If I set a reference consumption between 100 and 217 Wh/km, the calculated consumption always remains exactly the same. Only when the reference consumption is above or below this range is the calculated consumption on the route adjusted. There seems to be an error? I have also noticed that something must be wrong on the route from Erfurt Linderbach to Erfurt Herrenberg. On the outward journey it goes downhill, on the return journey uphill. However, ABRP calculates the higher consumption on the outward journey. I compared it once. In fact, the consumption calculated for the outward journey is pretty much the same as the actual consumption on the return journey and vice versa. I would be pleased if you could give me some feedback. Kind regards Pascal Haß
