One small thing: When SeedFinder gives you multiple seeds, note the number of frames. Usually when I soft-reset for Mewtwo, I encounter it as quickly as possible yielding a frame usually around 500. Let's say it gives you 3 seeds with frame counts 1000, 200000, 3500000. You pretty much know that your's is 1000, since you haven't been in the game an extreme amount of time. To verify, though, just copy the seed it gives you into RNG reporter and search for your spread. Hope that helps!
