Weve been down this road before, unless your aiming your camera at a full screen 18% reflectance subject the meter will over or under expose the subject. the only way you could be accurate is if you manually compensated the meter reading based on the KNOWN reflectance of the subject and that is nearly always UNKNOWN.
you WILL miss due to film, processing, metering, shutter. They are all REAL ERRORS always present. You may be satisfied with your results, but if you think that you are actually getting ALL your actual exposures within 1/3 stop of perfect, you are mistaken. There are WAY to many sources of exposure error in the system for that to be even remotely possible.
