As Master Pongo informed me, this is in the_skin_by_pongo.zip and more specifically in navigatemap.ui file, line 433 (latest iGO Luna skin by Pongo update 10.10.2022):
<BOX orientation="vertical">
This line can be changed as below:
<BOX orientation="vertical" paddingtop=7 paddingbottom=10>
I found the above settings as the optimum, concerning current speed/overspeed percentage indications placement (inside the 3D current speed/overspeed frame).
The original zip file with the modification. Like not needed. This is Master's creation and manipulation

Spoiler: current speed/overspeed percentage indications

I am creating my 3D icons using the same icon dimensions as Alain's svgs.
