hope your example relatively late production
for the first eight or ten years of production the stands were neither self-centring nor self-dishing, even thought they claimed to be
this was due to play in the arms at the pivots
owners learned retrofits such as adding brass washers to the arm pivots
finally, after ten or twelve years of user feedback the manufacturer fixed the problem
