People who are looking for N-types will have a lower probabilities and to a lesser extent, T-types aren't as common as F-types so relative success becomes somewhat obvious although not as accurate as 0.995. The chances of running into a compatible dual is even more remote because personal baggage can be way harder to tolerate. It's a little easier to find people where both can tolerate each other's baggage but even that would be far from a slam dunk. Rather than use type as a search engine, use it as a tool to understand one's partner because type dissonance is often minor when compared to other potential problems.
