That's amazing! I was working through doing - well I would say something similar but looking at your code it wouldn't have been close. :) This will at least let me move forward with compilation - I had already forked things to start working on it, so I'll let you know if I see any issues.

Thanks Ed! FB22335457 has been filed. And yes - it's quite an expression! I'm working on simplifying it into sub calculations or seeing if there's any other optimizations we can do.
