Question...when the slots are lined up does the screw head shape fit the shape of the action as needed? And how much over-timed do you estimate?
There is room for the screw head to be more fully seated, which you can do if you go beyond timed. The different surfaces have become squashed perhaps.
I would say that on average that these are able to point to between 2 and 4 o'clock when fully tight. Maybe I'm anal, but it doesn't look good, and the tops of the screw heads are no longer flush with the surface that are resting in when they are over-timed, or under-timed for that matter.
