Actually the Graham "level" does have some value, but not for azymuth, which is an axial tilt function. The true value is as a reference when jumping between different thicknesses of pressings. If you set the level for a 120g pressing and then adjust SRA from there you can determine the offest from zero. Then when you shift to a 180g (or 200g) pressing you can find your reference (level) and then dial in your offset. Guaranteed to have a constant SRA, no matter what thickness pressing you are playing. But, c'mon you knew that already!
