Variance, sure...but I'm always downswonging when I load up Stars...I'm thinking it's a bit rigged for realz. I've played tons of poker in my life and I always run like this on one site...hmmmmm? There are some horrid overagg players on Stars, but they always manage to beat me when I'm 90%.
Just one example of how my sessions tend to go on there. I have notes that this player is an overpair donk, I put him on QQ/KK likely without any draw...and kaboom, away we go.
ahhhhhhhhhhhhhhhhh datsa nice
feels sooooooooooooooo goooooooooooooooooooooooooooood
)(#$*)(#$*#@$@ ima rape ur family
meanwhile, a few hands earlier I lose AA<KK on AKxx board aioturn vs aggro donk...le sigh
