Closeness centrality - is measure correct?

When using the Kite_example file I notice that the measure of The most closely connected (Fernando and Garth) is the highest, rather than the lowest - could anyone explain?

I'm not sure I understand your question, but there are two ways to compute closeness centrality, as indicated in this Wikipedia article:

NodeXL uses the reciprocal version, so those vertices that are closest to the others have the largest closeness centrality.
