If it helps ease your mind - about 6 of my 16 uprights are off their foot/paver. I didn't catch it in time while doing an overnight fill. We use precaution while in the pool - making sure no one kicks/pushes off the side, no one jumps in from one of the uprights, etc. I think any AGP is going to have movement just because the majority of the pool isn't braced by anything like an in-ground would be.
