What does "potency" mean?
If substance "A" is considered 100 times as "potent" as substance "B", it DOES NOT mean that it is better in ANY way than substance "B". It ONLY means that it takes 100 times as many milligrams of substance "B" to achieve the SAME results as substance "A". It is the results that matter, NOT how many milligrams it takes to get those results. The pharmaceutical companies have, for many years, used this confusion about "potency" to sell more, and more, expensive drugs that do the same thing as the old drug but, because they are "new" and more "potent" can be sold for a lot more money.
