Yes I would follow this procedure as close as possible. Most brake pads come scorched on the face to provide quicker break in times. The EBC pads are not scorched and actually have a layer of "break in coating" which is a super high friction level material that is supposed to bed into the rotor giving you ultimate performance.
The first 80-100 miles are important in getting to coating worked into the rotor. Be soft on them for a few days.
The full width contact patch they are referring to is the rotor face. Make sure the pad is wearing evenly.
After all this, do the 10 hard stop bedding procedure, let them cool and you should be good to go! No need to drive around for 800 miles, that is more for used & beat rotors.
See the "band" going around the rotor face, this is what you are aiming for.
Will the band still be the same for the type of rotors that come with the Stage 5? (Btw, are those types called slotted, etc? Do the spiral lines have a name that go around the rotor?)
