Distance from barline to first note of bar

[Jakob Pedersen via LilyPond user discussion]

Dear everybody,

So I've been wondering about the distance between the barline and the 
first note of a measure.

I'm not an expert typesetter by any means, but it does seem to me that 
the gap is narrower in lilypond scores than in examples by Gould, for 
instance. I've come up with this comparison:



The example on the left is from a chorale I've made (attached.) The 
Gould example is from page 468 of the 2011 edition.

The ratios of staff height to gap is 3.648 in lilypond, but 2.518 in 
Gould. That means the lilypond gap is ~0,69% of the Gould gap, close to ⅔.

That's quite the difference.

Have I done something that diminishes the gap? (see attached chorale.ly)
Is the smaller gap by design? And if so, would it preferable to have it 
bigger by default?
Can the gap be extended by some ratio of global staff size? (I'm 
assuming a fixed increase would make problems with scores with a larger 
basic staff size, like my own.)

I would appreciate any insight on the matter, both with regards to 
desirable typesetting, my attached example, and how lilypond deals with 
this. (I have yet to figure out how to read the detailed documentations 
of engravers etc.)


Best wishes,
