I took some files sample of games currently installed on my computer ...
1) Game = BAK / File = *.upk
2) Game = BAK / File = *.usm
3) Game = Dirt Rally / File= *.bk2
4) Game = Dirt Rally / File= *.pssg
5) Game = MGS5 / File= *.dat
6) Game = MadMax / File= *.arc
7) Game = ProjectCar / File= *.bff
You should be more precise, to specify what types of flows detecting in input, and what types of files, so use your new compressor with the desired result.
Except the positive result of the first test posted, with all the others I have not gotten the desired result.

Edit: Test Only Upk Files
But here the situation is different, I wanted to test the only files *.upk, that in their results they have given a positive result to the new "PZlib"
Amazing speed in comparison to the use of the last precomp045, and better compression compared to reflate 1.4 ...
