 That is my understanding to. But that is for a weight increase of roughly 16% (from 3000 to 3500 Kg) If we use this info to make a ballpark estimate of a 6% increase as was the case for the Mustang (from 9680 to 10280 lb) we discussed earlier, we get around 1 Km/h for the Me109 from Kurfurst diagram.
That tabs pretty well with the 1.4 Km/h that Harri and I calculated for the Mustang previously and shows that weight within reasonable bounds is not an issue at low level high speed flight.
