Think of it like quantum indeterminacy. Either UFX400 is Kentmere 400 or it isn’t. Currently it exists in both states, some people buy one, some buy the other, liking the results they got from the one they bought. Some people believe they are the same, and buy either, but not having certainty makes them potentially separate products. Once official word leaks that they are the same, the wave function collapses, and the market sees them as the same, and interchangeable. That effectively shrinks the market for both Kentmere and UFX.
