Audi e-tron GT: Charging power very poor

Servus Together, I had now several GT RS for testing (I bought one I get in Sept.), and I noticed the very poor charging power. I also met people at the IONITY loaders who loaded a standard GT. as follows: GT RS SoC between 40 and 60 percent -> Charging power fluctuates around the 104 as a comparison: etron S -> charges with 140 and goes up to 150, similar SoC. Vehicles all driven on the highway, with appropriate preparation the g with 2 different GT RS, the charging power was only below 20% good (240), but also went down quickly, partly below 150. Last week a GT hit that came from Lake Constance, and had charge at the AB next to it: 104 at SoC 55% and my etron S next to it at the same percentage 150. Does anyone already have one here and how is the charging curve? Don’t find that exactly good, with the possible charging power. Thank you
