David Stuckey responds:

Ron, that 10 seconds does include the dissolve time from the previous slide
and next slide.  I usually dissolve to the tempo of the music which can
vary.  I use approximately 1.5 to 2.5 seconds.  So a slide may be on the
screen fully, without overlap, for only 8 seconds.  Of course, I am
absolutely ruthless with mounting and anything that ghosts, twists etc.
etc.  I aim to make my shows no more difficult to view than a 2-D show. 
This can lead to a lot of heartbreak when I throw out a top image because
it cannot be projected to my satisfaction.  I did produce a show where the
slides scooted along at 7 seconds each but people commented that is was too
quick.  Certainly the pace needs to vary and I take great delight in
programming a change right on a dramatic piece of music.  Come to ISU and
see for yourself! :-)
