Cool stats tool. It's nice seeing the odds going first or second and expected numbers of bricking during weekend ranked.
I think using a hypergeometric calculator and punching in the numbers would get you with in 10% relative to what actually is the odds.
The weekend ranked tab is very useful in my opinion, really liked this outcome!
The values were simulated using 20k samples, so there might be some deviation from the true value, around +- 0.7%.
