It does not prove the new position is the correct final setting. What the pattern is telling you Measure before the observation and re-measure at several points afterwards. One fixing can close one gap and open another as load transfers through the frame. There is an important mechanical reason why this can happen. When you tighten one frame fixing, you can pull that part of the frame towards…
