This time, you omitted the overrides to prevent padding and 
staff-padding from influencing the test:

%%%%
\version "2.19.45"
notes = \fixed c''' { \ottava 1 f4 4 4 \ottava 0 f, }

{
  % Make sure these properties do not influence
  % anything while testing outside-staff-padding.
  \override Staff.OttavaBracket.padding = 0
  \override Staff.OttavaBracket.staff-padding = 0

  \override Staff.OttavaBracket.outside-staff-padding = 0.56
  \notes

  \revert Staff.OttavaBracket.outside-staff-padding
  \override Staff.OttavaBracket.extra-offset = #'(0 . 0.1)
  \notes
}
%%%%

Mind you, this is all purely a test scenario, not a practical one.  In 
practice, you'll have all of the spacing properties to contend with.  
While it might be possible to adjust a single property to effect the 
change you need in one spot, that same property might be not be 
sufficient in other situations.
