If you were sacrificing chickens during your bed-in process, therein lies the problem. ALL professionals KNOW that it's GOATS, not CHICKENS!!
Bedding-in the brakes is all about the desired result, not the process itself. What you want is a nice, even transfer layer of pad material onto the rotor, and the only way to do that is to get the stuff HOT. I can't bed on the street, so I simply go out for the morning warm-up session with my ducts taped closed, and drive like a maniac until I can feel the pads themselves start to fade (press the pedal hard, car slows gently), then run a cool-down, and park it. Done. If done correctly, you'll have a nice even grey/brown/purple haze on the swept surface of the rotor. Ideally, I would roll the car a few feet every 5-10 minutes during the initial cool-down, but with having an instructor's schedule, that's not always possible.
The progressive speed thing simply guarantees that you have functioning brakes (the slow speed stops), and begins to get some temp into the system, until you go to the high-speed portion (100+MPH panic-stops) which actually does the transfer. The big key is not to drag the brakes once you get the transfer done until things are cool, as that will wipe off the transfer layer. Also, on a pad-only change, there's no real need to re-do the bedding, as the layer is still there on the rotor.
