For a helix with constant radius, the pitch is related to the slope of the constant tangent with respect to the axis:
pitch = PI * 2 * radius * slope
So as the radius of that helix decreases, with constant pitch, the slope increases.
The slope of a helicoid increases closer to the axis.
For a helicoid created from sweep of a variable pitch helix, and intercepted with a surface of revolution that has variable radii,
the SLOPE at some point on the surface helix, could possibly decrease, stay the same or increase, w.r.t. the variable pitch helix. (?)

How could this script be modified to use slope angles instead of pitch units?
The approach I have been trying is making an arch with my desired slope progression curve, then wrapping it around a circle using the deform tool (the helix I want to make is constant radius, variable pitch). However when I show curve points of resulting helix, it isn't as accurate as I would like.
