I believe him. I've seen screwy VOA results on here. My Red Line one for example from Schaeffers said over 5000ppm calcium. Where other labs have shown around 3000. Noticed same thing with other labs/VOAs as well and other additives. So it must be a (high) percentage variance and that would be why wear metals only vary a few ppm(because there is less to begin with) but additives are all over the place.
