How many times have you put your ruler on something and had to do the mental math to figure how much up and down to go to get equidistant points from the center?
The scale on the end is nice when you have to keep the ruler square to a surface, or you don't have the room to drop the ruler in from the top.
who doesnt have a stair gauge, tramel points, or a 6 inch ruler the middle is three. if math is a challenge. or use a piece of note paper folded in half no numbers involved
We old school drafters used to split the distance between two lines by laying a scale at an angle with a whole number over each line. Then it was easy to mark of halves, thirds, quarters, etc.

I remember where someone needed to divide a space into a set number of roughly equal points, and they took the waistband from underwear, marked off inches on it and stretched it out across the space.
