Seems to me that there's either more air or a leak. Loosing any fluid?
If using a helper, only push the brake pedal once, then while they're holding it down, crack the bleeder. Pushing the pedal 5 times may be aerating the fluid.

I usually do it myself, but I have a small bottle (brake bleeder kit) Tubing goes from the bleeder screw, under the fluid level in the small bottle. That way your pushing out air, and not taking the chance of introducing air in through the bleeder screw.
