Laura, I asked someone on the Elna list about how long it takes for a flat spot to develop and he's worked on LOTS of them. He thinks that only about a week, maybe less and a flat spot develops. It may be a small one. And then you sew and leave it again (new spot) and new flat spot. And it maybe doesn't make the jackhammer sound of one really flat area, but begins to start sounding louder than it should and you don't even notice it. Eventually, you have one loud machine that in the 50's and 60's would be brought in for service, leave like smooth running machines and the machine repair people were thought to have done miracles:>
