I'd expect the same from a new wheel/new pad situation for rim brakes. The braking improves slightly upon wearing glazing on the pads off and wearing down the polished surface of the wheels. Slightly is the key here. If you have to go for the various distances and number of stops reported here and resort to black magic, you aren't breaking the system in, you are waiting until you get used to how it performs.
