Re: Strange TextScript behaviour?

[Mats Bengtsson]

I don't follow exactly what you try to do. However, the vertical position is
determined based on one of a number of different rules, depending on which
one sets the strictest limits. In your case,
- The staff-padding detemines the minimum distance to the stave.
- The padding determines the minimum distance to the closest
 object (stem or stave or note head or whatever). In your particular
 example the stem is the closest object.
- The slur-padding determines the minimum distance to the slur,
 if the text script extends above the slur. In your example, the difference
 between "1" and "11" is that LilyPond thinks that the former is only
 above the stem, not the slur, whereas "11" extends so far to the right
 that it's considered to be above the slur.

If you want a fixed distance to the stave, just set a large enough value
of staff-padding, so that this setting dominates the other ones.
Also, instead of using the extra-offset to change the horizontal position,
you may want to set
      \override TextScript #'self-alignment-X = #RIGHT
As you will notice, this setting changes many of your conclusions, for 
example
since LilyPond will no longer think that any of the text scripts is 
above any slur.
I recommend you to remove all your other \override:s as a starting point.

Note also, that your score will look different if you upgrade to the latest
development version (or when you upgrade to version 2.12 when it will
be released some time in the future).
