In Octave's own code base we only use two

a Texinfo wizard to help us set that up.
I see some changes in the PDF output when using different values
of N for "@exampleindent N", but the spacing seems wider than the
documented N ems. Nothing seems to change for Info output. This
looks like a bug in texinfo to me.

I did some experimentation. The spacing used in the PDF is measured
in ems, a typographical unit that used to be the width of a capital
'M', but is now the width of an em-dash by definition. While the
default value of @exampleindent is 5, in TeX this is rendered as 0.4
inches. However, if you specify the value as 5 then TeX renders 5
em-dashes which is actually larger than 0.4". In the figure below,
the first indent is "asis" which is 0.4". Then there is a cascade
of 0, 1, 2, 3, 4, 5. I propose setting the example indent to 2.
The value of 3 produces an indent which is already larger than the
default which itself I consider too big. Unfortunately, fractional
values are not allowed.
We could also consider changing @paragraphindent for improved
readability.
