Gravity is a factor. Placing it vertically/horizontally makes a difference. Magnetism would be a very important factor were it not for the mu-metal shield around the CRT. Whether it deserves to be called "wayyyy off" is a matter of opinion. A change of rotation of one, max. two minor divisions across the horizontal would be normal under normal conditions..
