But why would that give greater accuracy? Most times the problem reported is that the blocks come out too small, not too large, so a looser stitch would be better if that were the case.

I watched an Eleanor Burns video where she recommended a high stitch count per inch (15?) for sewing strips that are going to be cross-cut, so there's less chance of the threads coming loose when they are cut. I understand doing that, but how does it contribute to accuracy? Inquiring minds need to know.
