Yes, this seems to be a rule of thumb mentioned in some literature.
Unfortunately, I have not allowed for such a weighting factor in the
clipping code. It might be possible to add, but it would be
some little work, as it would essentially have to be done by adding a
value scaling factor to the rspl code (since the internals is too
tightly tied to the 3D/4D geometry.)
It might be worhth a try ...

Gerhard
