Found the JEDI jclCompression library has implementations of BZip2 and GZip, so I've added those as options, and also added an "Average of all 3" option. The results from each of these are quite different, but they agree from a relative point of view; ZLib is always highest, with GZip next, and BZip2 usually lowest, but they're equally good at distinguishing between texts. The differences are noticeable, and none of them now agree with the results from NCD on Linux, which is odd; LZip did in my earlier testing. However, there are now lots of options for calculating the results, which is useful, and we should be able to figure out what provides the best algorithm by producing good human-readable output based on the results. That's my next task.
