Maplestory Myths - know any?

I have no idea how possible the following is, just a theory but:
Is it possible that the random number generation is based on a seed updated by the game itself? If it's not updated frequently enough, it would create these anomalies. You have the source code though, Fiel, so you would be able to tell for sure.

I feel like there should be some way to explain that type of anomaly, because I've noticed it too. Obviously "junk scrolling" doesn't work, but there's got to be something to explain why there's random instances where you see several of the same item all at once, or that low rate scrolling can succeed a whole lot in one go. I often see Gachapon messages of the same person getting the same item 2, and sometimes even 3 times in a row. In the case of equipment, it shares the same stats and everything. Seems like the random seed gets frozen or something, so it dishes out the same numbers.

Come to think of it, I have gotten 2 Lunar Dews within 15 seconds of each other, and Peridot hunters often claim the same, except with Peridots in lieu of dews.
