Pretty sure Ali-bear is correct.
Bedding the brakes in and normal riding deposits an even layer of
brake pad material on the discs. So stopping power is due to friction of pads on pad material, not pads on rotor steel like everybody since the beginning of time assumed.
One cause of "uneven" pad material distribution is riding hard, braking hard to get the brakes really hot, then stopping and holding the brake lever on. This keeps hot pads against a hot static rotor thus depositing a large chunk of pad material in that spot. You might be able to use Scotch Brite pads, steel wool, or sandpaper to carefully scrub the entire rotor surface (both sides). Then bed the brakes in the normal way.
Constant overstimulation numbs me; but I would not want it any other way!
