You're working too hard to solve a simple problem.  The _thickness_ of 
the layer determines the delay, regardless of the diameter of the star.  
It is a linear function, not logarithmic.

If you know the linear burn rate of your delay comp, you can determine 
the delay directly.

You can determine the linear burn rate by rolling some stars to a 
specific diameter (say 1/2") with ONLY delay comp, then burning them to 
determine the timing.  One-half the diameter of the test star equals the 
thickness of the "delay layer".  If the star were coreless and 1/2" in 
diameter, then the delay layer would be 1/4" thick.  Time to burn divided 
by thickness = delay per inch of thickness.
