SWC is currently not running on a provably fair shuffling algorithm?
this clearly explains why some users tend to hit their 1-2 outers on the turn/river more often than not.
The shuffling algorithm is public and generally accepted to be the most fair way to pseudorandomly shuffle a virtual deck of cards. It's the same algorithm used by all trusted poker sites.
"Provably fair" is a term being used to mean that the entire shuffle can be reproduced with a seed that can be publicly known or reproduced and independently verified. The seed of each shuffle is currently neither reproducible or public.
