[2022] Rigged RNG or confirmation bias?

I have been now playing on unfair and somewhat been recording rolls (1s and 20s only)

after 40hours of playtime, I have come to a following observation; My characters seem to be rolling more 1s than 20s. about 30% more 1s.

I began recording these because as I used Camellias hexes that allows and forces rerolls, I noticed that my guys often rolled double singles in a row, while enemies often bybassed protective luck by rolling double 20s

Overall I also FEEL, that my characters tend to be rolling under 10 most of the time, though I can often hit with 5+ so its not a huge issue, but as I have not made any recordings on the matter, I cannot say if its really the case or just confirmation bias.

Any thoughts?
