Huh. Interesting. As OP notes, they "only" get 150 rolls for each AC, so there's some uncertainty.
Specifically, there seem to be 3 conclusions:
1.) Karmic Dice result in an average roll of ~12.5, higher than the expected roll of 10.5. This is fairly significant, as there are ~650 rolls in each category (Karmic vs non-Karmic) = small uncertainty.
2.) Karmic Dice result in more crits. This also seems significant; in every AC category, Karmic Dice crit more often than non-Karmic Dice
3.) Karmic Dice result in more crits against higher-AC characters.
However, there are some issues with the 3rd conclusion.
1.) Both "AC 23, Karmic" and "AC 23, Non-Karmic" roll sets show anomalously high crit chances.
- For AC 15-21, the Karmic Dice crit chance is 7-10%, but the AC 23 rate jumps up to 15%
- For AC 15-21, the non-Karmic Dice crit chance is 2-3%, but the AC 23 rate jumps up to 8.5%.
Both Karmic and Non-Karmic sets show a jump of ~6%, indicating it's not necessarily true that Karmic Dice alone result in being crit more often at higher AC values.
2.) With only ~150 rolls in each section, the # of instances of any single result is much less significant. A chi-squared test rule of thumb is the expected occurrence of each result should be greater than 5, and 150/20=7.5 which is approaching that limit. The expected 7.5 rolls could easily randomly vary to 10 or even 15.
Edit: Also, theoretically any roll bonuses should be applied to PCs & companions, so you'll roll higher against enemies.
