That last statement is a little confusing to me.  If the advance
knob did not turn all the way, you wouldn't be able to take the
next shot--unless either your Realist lacks the double exposure
prevention feature, or you intentionally set the camera for a
double exposure.  Or do you mean to say you are sure that although
the advance knob turned all the way, less than 10 sprocket-widths
of film were actually advanced (resulting in significant frame
overlap)?

Yes your camera could be starting to have problems.  What film have
you used in the past?  It has been mentioned here on the list (in
connection with frame overlap problems) that different films are
more or less "slippery" and therefore easier or harder to "pull"
from the cannister.  Kodachrome, negative films, and bulk-loaded
E-6 are thought to be more slippery, while retail E-6 films are
thought to be harder to pull, if my recollections are correct.

Have you used Piper's recommended test to determine whether you
have the older (more susceptible to breakdown) or newer (more
reliable) film advance mechanism?

Hope this helps.
