Of course the obvious did escape me: One can use the cartesian form of a curve formula also.
As long as there is a function f(z) = 0 for points on the curve, |f(z)| = delta describes
a point off the curve (for delta != 0).
Another great tip. Thanks for sharing it. This one looks like it would work for curves with loops.
For folks trying this on their own, some of the formula is missing. To get the Deltoid_Example to work, I pasted the xx,yy,a, and distance equations into the formula for Astroid_Mset_v2.
