on some patterns, it would not matter, as long as you had the same consistent seam. but some need that "scant" for the "turn of the cloth" that a seam takes up as it is turned.
sew a sample block, or piece of a block that has lots of seams. see if it is the size it should be. then make your seam smaller or larger as needed.
I think the easiest way to test your seam allowance is to cut 3 of 1 1/2" strips of the fabric you will be using.(about 4" long) sew these together lengthwise, carefully PRESS. measure--the whole piece should be 3 1/2" wide. if larger,you need to take a bigger seam. if smaller, you ned to take a smaller seam. I keep pieces to sew before a major project, but to keep me honest.
