>The big question, it seems, is what exactly the constants are at each question mark. I hate to do this, but mathematically it wouldn't matter what those individual constants are since they're all being multiplied together. The equation you want probably looks more like S = ?I + ?F + ?P + ?T or S = I^? x F^? x P^? x T^?
