Jesus Christ you must have been bored at work . . .
And yea losing any number of flips or 80:20s is possible but over a decent sample loosing a ton in the row is probable, or for sure.
Also are those numbers made up cuz (1/6)^30 is a really really small chance and I doubt you did this millions of times. Like 4.5 e-24 unlikely.
Either way variance is gross but it's what keeps the poker economy alive so we should appreciate it.
