I'm more forgiving of what may look like spaghetti code or dead code in this context.
First, color math isn't always the same as plain math.  Second, there are some
oddities and exceptions in the Poser system that are understood only by BB.
Third, it's often useful to set things up in a standard template form so you can
change or add things into known positions.  It's easier to keep track of several
"variations on a theme" by setting some variables to zero, rather than by changing the
pattern of the nodes.
