That works pretty good!  There is not a lot of extra power left over for 
web cruising but it does ok.

One thing to really watch is to use "real" values.  There is no reason to 
scan Cp from 0 to 100nF in 0.1 steps.  Since MMCs come in step sizes, just 
scan for those.  In my case, I am just going from 75nF to 525 nF in 75nF 
steps since that is the smallest step size I have for the real MMCs.  Same 
for Lp.  You can only tune to say 1/10th of a turn, so no reason to scan 
every /10 inch ;-)  So if you keep the increments fairly big and practical, 
you can speed things up about 100X!

Cheers,
