Also, note that both of your lenses are in the - range. That suggests that the problem is more with the body than the lenses. For example, it is entirely possible that both of your lenses are really + tolerance, but your body is out of spec -. Speculatively, your 70-200 might be +8 and your 24-70 might be +0, but the body might be -16, leading to a net adjustment on this particular set of gear at -8 and -16. And in that case you might find that your 24-70 might be dead, spot on using another body.
Bottom line: the absolute number you see in the adjustment does not tell you enough to know which item(s), if any, are out of spec.
