for paper piecing, normal. It's a big reason I don't cut my PP pieces based on the pattern, I've found they often have over 30% waste. I had a lot of fabric left over from my CMIYC quilt, the directions had you cutting rectangles for all the shapes, when they are all triangles. I cut mine as triangles to start with.
When I did the Fire Island Hosta, I cut WOF and did not precut individual pieces. I was using from stash and knew I would quickly run out of fabric if I followed the pattern cutting layout.
