Thanks Pikcachu for the extended response. Looks like that's from elsewhere on the EBC site, and has more detail than the link I posted. The 'full contact' before bedding part makes sense, and explains a lot.

So, how do you know for sure that the pad is completely touching all of the rotor before doing the bedding runs? I'll be putting these on the existing rotors, which are already shiny/worn across their face. Does the 'brake in' red coating mark the rotors in some way? I suppose I could also just look for slight surface rust, but the BMW rotors don't rust anywhere near as much as other rotors I've had, making it hard to see.
