Edit: The highest value you got in your non-kaiten test was 457, which means the highest number you should get in your kaiten test should have been ~685... yet your highest kaiten dot tick was 857. To get 857 from kaiten and the slashing debuff alone your max crit dot for non-kaiten should have been around 571 damage. Of course there is a lot of variance in getting a crit at the same time as a high damage roll for a given tick, but going from 450 to 571 goes well beyond that.
