I have bled brakes thousands of times and rarely if ever have I seen gravity bleeding that didn't have the air bubbles you are experiencing. There is not pressure on the brake hose from the bleeder to your can, so the air bubbles are walking themselves up the hose.

Did you pump up the pedal before you started to bleed? If not, that is the gap you are seeing between the pad and rotor. Even if you gravity bleed, you still need to pump up the brakes a bit. Bleed some, then pump them up again.

I use the stick method. Grab a broomstick and wrap a lot of tape around the end. Get int he car and pump the pedal. While holding the pedal down, put the stick between the pedal and the seat. Get out, open bleeder. That was before I bought the Speed Bleeders...but it still didn't take me 5 hours.
