Hi Ben,

I think this shouldn't solved by any padding at all but by adjusting the
distances between systems.
The separator will always be vertically centred between systems for optical
reasons, and if a bar number happens to collide with the separator, this
just means that the systems are too close together.

In your example, the bar numbers take considerable space (relatively large
font, boxed with lots of padding) so that they even may effectively serve as
a system separator.
As the bar numbers will always be present at the beginning of a system, the
best solution (in my opinion) would be just to increase the overall
system-system-spacing (in the \paper block) to give the score an evenly
spaced look.

}

  #(set-paper-size "11x17")
  top-margin = 15\mm
  left-margin = 20\mm
  right-margin = 15\mm
  bottom-margin = 15\mm

  system-separator-markup = \slashSeparator
  system-system-spacing = #'((basic-distance . 18)
                             (minimum-distance . 17)
                             (padding . 1)
                             (stretchability . 12))
}
