  There is a one-to-one correspondence between strong inversions on knots in
the three-sphere and a special class of four-ended tangles. We compute the
reduced Khovanov homology of such tangles for all strong inversions on knots
with up to 9 crossings, and discuss these computations in the context of
earlier work by the second author. In particular, we provide a counterexample
to [Conjecture 29, arXiv:1311.1085] as well as a refinement of and additional
evidence for [Conjecture 28, arXiv:1311.1085].
