Hmm. This perfectly sums up my understanding of your program, Ed, and therefore I will unlikely able to provide any kind of feedback.
Before you threaten to totemise me: does this program allow modders to plug in various formulas ruling any value in the SEIV files? For example, is the purpose of this program to automatise a geometrical suit ruling the cost of devices? (Such as what SJ seems to have done for his latest mod)
If so, I can indeed see its usefulness for modders (well, as long as they can understand the whole array of mathematical functions better than I do; I flunked maths at kindergarten after all). If I am wholly mistaken, I guess it is simply too complicated for my poor mind.
