On ''bench'' bleeding on the car, it may be more important to release the pedal slowly, maybe even holding it down a little first, giving the air bubbles a chance to rise up where they will not be sucked back in. Also same thing at the corners.
At the corners, better yet, go with the tedious 2 man (1 wife?) procedure of closing the bleeder on the return stroke to insure no air is drawn back in. That is what I always fall back on after the tubing falls off the bleeder or slips out of the fluid container. Since I don't play with the brakes much, my wife tolerates it. I like the brake pedal goes down once, open the bleeder, close it when the flow stops, release the pedal, and a single pump again.
