I'd like to see what would happen if you randomized the scaling factor between
0.999 and 1.001.  I have a hunch it wouldn't look so much like broccoli.

Doing that wouldn't make a whole lot of sense because it completely 
negates the original concept. That way the scale factor on both parts of 
the sphere can be either up or down.

More often than not, one side will be bigger than the other.  That is all the
process requires.

The way you're doing it, you should at the very least make your factor a random
amount.

From the page where I got the idea, it looks like he may be using a constant
value but randomly choosing whether to shrink or expand.

still, I think the process will work as I've stated.

A.D.B.

I don't know which method is better because each relies on one or more 
random streams. The best way to figure that out is to run a series of tests.

My greatest concern is quality of result, rather than most efficient solution.

3D art us usually a compromise between the two.

I'm currently working on a solution in C++ that will output a PoV-Ray mesh.
I'll post the results when I get the kinks worked out.

Regards,
A.D.B.
