People are missing the whole point and trying to justify a blatant error. Okay, it's fine if you still like it despite the suckout, but I wouldn't spread misinformation by saying it's not there, or it's just a mere dip, let the listener decide if the suckout bothers them. But don't say there isn't one just because one happens to overlook it.
Who?!? No one has denied seeing what the graph depicts, but you're desperately playing devils advocate. Then you say "let the listener decide if the suckout bothers them." Seriously? Newsflash, we, the listeners, have already expressed our views, and no measurement is going to change that. You, on the other hand, have a very hard time accepting that many of us actually admire the way the SM64 sounds, and that's blatantly obvious.
