"WebSo for a consistent-width gap, this "light and ruler" test would make the issue appear worse in the centre, which naturally makes us think "the bed is warped". The wide angles of the light sources also means that very little light is hitting the gap perpendicularly or straight-on, and instead hits this gap at an angle.
