I had 40.2% critical strike chance for our raid tonight. Throughout the raid, I shot 281 shots. 87 of those shots were critical strikes, meaning 30.9% of my shots fired were critical strikes.
Using a simple binomial probability calculator, with .402 being the probability of success (or crit) per shot, number of trials (shots fired) being 281, and number of success (crits) being 87, there was a probability of 0.000297571, 0.0297571% or 1 in 3360 chance of this outcome occurring. So either there is something funky going on with crits for hunters or I got supremely unlucky
