Electrek's recent article says: 'Audi is right. Their approach does offer significant advantages, especially if you are looking to get a full charge out of the charging session.' but then goes on to say about the Tesla advantages. However it doesn't say that these advantages blow the E-Tron out of the water!
The graph below shows that just by holding onto the charging rate later in the cycle doesn't mean it beats V2 Supercharging, let alone V3.
I also added in worst case scenario with the Model S SRD at 120kW, but that has a much smaller battery than the E-Tron.
Why doesn't the E-Tron overtake the S SRD? Because at 80%, just before the E-Tron starts to taper dramatically, the S SRD is at 60% and still has a decent 276mph charge rate vs the E-Tron's 304mph.
Unfortunately the E-tron's dismal efficiency loses Audi the battle, maybe that's where they need to concentrate their efforts.
