---330---N---30--- (actual heading)
-----330---N---30--- (desired heading with corrective offset incorporated)
isn't it something like ~10deg x cos(alpha), with alpha being the angular offset from an east-west orientation (for example west being 0 and east being pi, have I got it the right way?)(*). The "about 10deg" are taken from a post by luthier, regarding compass offset.

Just playing around with my very shaky rememberances on considerations regarding the magnetic poles from school...

(*) alternatively, probably better/more intuitive: 10deg x sin(beta), beta being angular offset from a north-south orientation...
