I second this- I would love to conduct some experiments with karmic dice on and off, and on multiple difficulties to see if that influenced odds in any way. As was discussed in another thread, it is entirely possible there was confirmation bias, but it seems like I am noticing two things happening more than probably should:

1. Nat 1s and nat 20s

2. Rolls that fall just one or two short of the threshold despite the threshold not being particularly high (I seem to get 9s on roll v 10s often)
