I get @millercarbon because from the outside to the inside - particularly with a weight/screw-down there is a curve/dish to the record. That said the hi Fi news adjustment is quite useful. Dr Feickhert at a talk informed the audience that mc’s almost always have a sideways tension on the cantilever by their nature/design. Shame there is no cheap plug in to check - both fozgometer and feickhert software aren’t cheap😢
