Marc may be right with the recommendation for some good-light testing.

The four new uploads show that the focus should have been on your red dot each time, assuming your were not doing a focus-and-recompose.

The kneeling drummer is an interesting example due to the table behind the drummer being in focus (not the far wall) at roughly the same distance back as the drummer and wall in 404 and 405. To me, this suggests a possible back-focus problem that should be tested for.
