I've often misunderstood what /padding/ is really meaning:

- keep that distance above the last object/item/whatever (the normal staff?)
- add this distance to what has already been calculated

and my understanding now is:

- keep at least that distance from the normal upper staff line (and not from
the topmost note)

usually the collision avoiding mechanism moves a text script upwards
sufficiently  - only if you want surplus vertical space above the ledgered
lines you have to add more padding space (and this will be counted from the
normal upper staff line)

btw - the section you mention wants to explain how to use variables - maybe
the example(s) are a little bit unlucky?
