How is sand/oil roll winners determined in Syrcus Tower?

MMOs would be the an interesting case study for this.
"I didn\\'t get this thing with a 20% drop rate in 50 runs (which turns out to be less than 20) therefore it\\'s broken!"

I hope you meant 20 runs, and not 'less than 20%' xD I was a little confused by the post until I thought you probably meant they were overrexaggerating how many runs they had.

Even still, 0/20 on 20% sucks. In a perfect world they'd be 4/20.

It does suck, but this world is imperfect and math will never be exact (more precisely, probability will never be exact). There will always be that guy who got his atmas pre-droprate increase in one day alongside the guy who spent 2 weeks (doing 2 fates a day then coming to the forums and complaining about doing "hundreds" of fates) and only having 3, post droprate increase.
