• Is Stac compression really that bad?

    Hi! I have a version of the Stac compression technique on which I've been working, and, well, it sucks. A 13.8k file that is a text adventure for an old computer compresses to 7,801 bytes on Deflate and 7,364 on WinMount but, at last test, my rendition
    of Stac gave me 8,210 bytes. Right now, the only thing I'm doing that's not in the specification is Deflate's lazy mechanism where, if the next byte in an LZ77 scan produces better results, code the current byte as a literal. I have ways to make it
    better but prefer my renditions/enhancements of the XZ0 technique. BTW, I'm using the Wikipedia page https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Stac as a reference.
