Wrong consumption assumed when towing a trailer

ABRP has live connection to my car and is assuming a consumption of 511 Wh/km at 100 kph. However, I am using around 280 Wh/h at 95 kph. If I turn off live SOC for consumption it even calculates with 811 Wh/km, no matter what I put into consumption. This leads to either 2 stops on a 330km trip with a calculated consumption of 411 Wh/km or to 6 stops… turning the profile “with trailer” off and using normal profile, I do not need any stops… the trailer function like this is pretty useless. Any ideas? Thanks.
