Definitely the algorithm itself, but I anticipate that with some effort I
can reduce it to a broad case with coefficients and then just let them
modify the coefficients in the field. But at that point it would probably be
10-15 terms and floating point would be essential.

I'm secretly hoping that I can distill it to some sort of lookup table. Have
Matlab or Excel produce it and then transfer that to the system, but rough
calculations shows a table size of nearly a megabyte so that may not be an
option. Obviously no PIC can do that nativly, but if I use an SD card for
logging it may be possible to stash it there.
