i answered the comment you made on the calcs page. also multipliers are legit as long as they are specific and aren't contredicted, every calc is based previously scaled and infered figures, you can look on every calc, scaled distances move from one calc to another, in fact, by you're definition of calc stacking, no calc be legit, as i can divide any calc to at least two parts, which can be stand alone calcs, and as such cannot be based on one another...
