Klee:
You've guessed correctly. Since version 113 was published, which was more than three years ago, we've switched to using a high-performance software package called "SNAP" (http://snap.stanford.edu/) to calculate some of our graph metrics. In some cases, the package uses different formulas from what we were using in 113. For betweenness centrality, in particular, I believe version 113 was normalizing values, and newer versions of NodeXL don't do that.
