I got hold of a Mamiya service manual. Now the spot and average are matched when pointed into my light box. Ran a roll of film through and everything looks good. Happy I was able to get this one working well. Now I will get back to the final tweaks on the Vivitar

The problem was that often the little tang on the contact inside the bottom cover would eventually break off due to metal fatigue. In later models, the meter was on all the time the wind lever was pulled out (like a Nikon or Nikkormat). And to turn it off, you pushed the top button which brought the lever to the inward stowed rest position. You should be able to get a little better accuracy than 1/2 stop. I'd say that 1/4 to 1/3 is possible. I did.
