First of all, I'm lucky if I even get a winning can, let alone the first prize. Hell, most of the time I don't even get a capsule toy!
So...to answer the question in the title, what would you say roughly? 1000/1? 10,000/1? More? Or am I just really unlucky? Oh and I must say thanks to BlueMue, I found your video on yt (the one where Ryo wins the radio) so at least that's some consolation .
