Nice post, that equation format is very clear and easy to follow when entering.

A small suggestion is when making a post like this, it's useful to include one (or more) sets of data, with keying instructions, and results for a sample run, which both explains how it's intended to be used, and also lets the reader confirm that he/she has entered the equation properly.

This is good advice for all machines, but especially important for Solver Language, where it can be hard to verify exact entry (as you've probably discovered by now).
