I didn't analyze the Pearson's Square formula, but instead worked it out with a little algebra (see, it does come in handy, sometimes), and I got the same answer, 1.82 oz. So, the formula works.

But the concern I'd have is whether the "fortified" LH80 would have become too dilute and lost a lot of taste. That 1.8 ounces of tasteless PGA is a lot to add to one ounce of LH80! Going the other direction, it only takes 0.89 oz. of water to bring one ounce of 151° down to 80°.
