I identified a minor error in the way I was factoring in off-element kamihime into the damage calculation, underestimating their damage contribution (underestimating total team damage by about 5%). This bug only affects comparisons between teams with different numbers of off-element kamihime (e.g., a Fire group with Light Sol vs. a full Fire group). I fixed it for the main Constant Effects Calculator (Comparisons of different team configurations), but implementing this fix throughout all of the damage calculators is going to be time-consuming.

Until I get around to propagating the fix, don't use the damage calculator to compare teams with differing numbers of matching-element kamihime. The results of such comparisons won't be valid, except for the one calculator I fixed.
