I haven't done an exhaustive analysis, but the impression I got was that
lockup eliminates some motion but not all. So in a critical situation such
as macro or use of a long lens you might get from a C+ to a B, but including
aperture prefire would get you to an A- (assuming of course the lens is
capable of that).
Perhaps doing critical indoor work one should
- turn out the lights
- open the shutter on B
- wait 10 seconds for things to settle
- fire a free-standing flash
- close the shutter
- remove the barricades so traffic can pass the house again
- tell air traffic control to resume flights
:-)
