I believe you will see your new fluid at all the bleeders with less than one quart. Perhaps two quarts will account for extra to wash through, and errors in judgement about when the new fluid has arrived at the bleeder screw.

If you change the fluid often, you might use ATe's fluid available dyed in blue and gold, alternating to clearly see when you've bled all the old. It's only a dollar more a liter.
