I still don't think it's correct. It first says that
shortest-duration-space is set to 1.2 by default and on the
second line it says that the same property is set to 2.0 by
In the actual implementation, you have
        (shortest-duration-space . 2.0)
        (spacing-increment . 1.2)

In Section 4.6.3 "Horizontal Spacing", it says

"Normally, shortest-duration-space is set to 1.2, which is the width of a note head, and shortest-duration-space is set to 2.0, meaning that the shortest note gets 2 NHW (i.e. 2 times shortest-duration-space) of space. For normal notes, this space is always counted from the left edge of the symbol, so the shortest notes are generally followed by one NHW of space."

I guess that a number of the references to "shortest-duration-space"
should be replaced by references to "spacing-increment" or some other
property, but I don't dare try to correct this mess, since I'm not
100% certain about what you really mean.

no, it's correct. shortest-duration-space is wrongly named; it is a
factor. Space is
( log2( shortest-playing-duration/shortest-duration)
  + shortest-duration-space) * spacing-increment
