Well, you were right, but not for the right reason. The distribution has strong peaks at 33 and 22, which are one and two iterations of 2/3 multipliers away from 50. There's no peak whatsoever at 42 or 28. You just happened to catch the right spot between the biggest peaks, not your own peak. (And the peak at 66 is rather disconcerting; there's no rational reason for that choice other than innumeracy or misreading the question.)
