I have no evidence at all, no math, no hand histories nothing, therefor I can make no statements.
I'm just saying that I have not played at Paradise much (i only play there to clear bonuses) however in my brief time playing there I see enough quads to make me personally uncomfortable.
I could be suffereing from selective memory, like maybe the idea crossed my mind and then a random group of quads happened soon after and I was all "AH HA!" or perhaps I just witnessed a weird streak of them fully within the bounds of statistical normalacy.
So I make no accusations of course because I have no proof and don't wanna sound like one of those "My AA got beat 3 times! This site is rigged to take my $25!" nuts.
This was discussed by a few people on this thread
Thread
This thread offers no real proof of anything though of course.
