That's the problem with "computer" generated formulas, the paint mfg's have eliminated the ALTs and combined them into one "matching" formula to simplify their computer matching system, your best bet is either find an original paint sample you like and computer scan it for a possible match, or get access to some color keys from your paint mixer or the manufacturer to find the ALT that has the best match... but keep in mind even the best color match can be fubar'd by choosing the wrong primer base/value shade, painter application/technique, etc, etc...
