Second stringer layout is only required for closed
stairways, when you're not using a pattern and there's only one stringer
on each side of the stairs. The picture below provides you with an
excellent example of two brackets stair stringers that needed to be laid
out individually.

Using A Pattern For More Than One Stairway
If you're going to build more than one set of stairs that are going to
be duplicates or exactly the same, you should create a pattern. When I
was building more than a hundred stairways per job, I always used to
stair stringer layout patterns to increase efficiency.
Advantages For Using Stair Layout Patterns
I remember when I first started learning about real estate, someone told
me that there's only three things you need to know about a piece of
property. Location, location, location.
The same message can be transferred to stair building and home
construction. Efficiency, efficiency, inefficiency and don't forget it.
Stringer layout patterns, provide you with exact duplicates of the same
stringer.
Disadvantages For Using Stair Layout Patterns
If you're building more than one set of stairs that are going to be
exactly the same and you're not using a stair stringer pattern, you're
wasting time and could create variations in the other stringers.
Let me give an example of what I'm talking about. You lay out four stair
stringers and if you move the framing square a 16th of an inch in either
direction, while your moving the framing square, from one step to the
next, you just created a variation.
If you moved the framing square an eighth of an inch forward on one
stringer and a 16th of an inch backwards on another one, you could
create one stringer that was its least an inch and a half longer than
the other one.
If you need to lay out more than one stringer, place them on top of each
other, and make sure that they match the other ones. Otherwise you might
need to make some adjustments, before building your stairs.
