I've used this website for a decade. I always pull it out when I meet people who claim the difference is obvious and can be called almost 100% of the time (like my Japanese colleagues who wonder why I can't tell a brit from a French, a Belgian, a German, or, hell, a Moroccan!).
I've never met someone who got more that 8 correct. Usually, that turns around 6 (like I did), which happens to be what you'd get by doing a random choice out of three!
