Nope, karmic dice are off. Bedides, most people say it doesn't actually matter because they see no difference. For me, the number of nat 1's out weighs any other number I have ever rolled. Is it because of the difficulty level that the dice are skewed so badly? I mean, it's completely horrible.
example:
Number of Nat 1's rolled: 57
Number of 2's rolled: 7
Number of 3's rolled: 6
Number of 4's rolled: 8
Number of 5's rolled: 6
Number of 6's rolled: 7
Number of 7's rolled: 8
Number of 8's rolled: 8
~
Number of 20's rolled: 36
So let's do some statistical analysis here, assuming that these are actual values you recorded during a PT and not a hyperbolic number.
Let's frame this as a Bernoulli trial, where a "success" is defined as getting a nat 20 in one instance, and a nat 1 in the other. Given that N=107, we would assume that each outcome should happen five or six times (for simplicity's sake), thus, for a nat 20 or for a nat 1, there should be k = 5 or k = 6 successes, to equal the expected odds of 1/20 ([1/20] * 107 = roughly 5.3).
Instead, for the nat 1, we have 57/107= 0.53; the ratio between expected and observed is 10.6(!!!). For the nat 20, we have 8/107- for a ratio of 1.14.
We can safely conclude that this game is likely not using a fair die in that case, if these are actual values from an actual PT.
