"The sector teeth are also cut so that when the sector is adjusted to take out all backlash at the center of travel or straight ahead position, there will be slight backlash at each end of travel, thus snugness of the sector in the rack teeth in a straight ahead position can be obtained without sacrifice of perfect freedom at extreme positions, right or left, of the front wheels." Meaning at dead center you'll have the tightest mating of the sector gear and rack teeth (teeth on the ball nut) and as you turn to the right or left that clearance will diminish.
Rather than "diminish", wouldn't the clearance be better described as "increased"?
