You can only max out the 'Word Size' setting if you are able to max out the 'Dictionary Size' setting. So the Moral of the Story is this: When setting the 'Word Size' setting, make sure you scale it along with your 'Dictionary Size' setting. And, I bet I could have maxed out the 'Word Size' setting at '273' if I had enough RAM to set the Dictionary Size to '1024MB'.

NOTICE: The 'Word Size' setting DECREASED the sized of the archive as long as I had a large enough 'Dictionary Size' setting (as you can see, the file size went UP when I hit the 256 'Word Size' setting). The people at XLABS took this method, refined it, and devised the method that, according to their claims, does lossless video compression with a whopping 99.92 space savings. It is tunable with compression levels ranging from negative 5 (fastest) to 22 (slowest in compression speed, but best compression ratio). For example, here's some tests with the 'Dictionary Size' setting maxed out (for me that's 512MB until I upgrade my RAM) and the 'Word Size' Settings set accordingly: RITA suggested a compression method that, apparently, was far better than any of the methods that are traditionally used. Zstandard was designed to give a compression ratio comparable to that of the DEFLATE algorithm (developed in 1991 and used in the original ZIP and gzip programs), but faster, especially for decompression.

You can choose among Store, Fastest, Fast, Normal, Good and. If you scale the dictionary size along with the word size, you'll get a smaller archive. Regardless of the archive format the next step is selection of compression method. 'Choosing a word size that is too large can increase the size of the archive.'
