I'm looking for real world file/files where 7zip filters Delta/BCJ2/BCJ can be applied, actually for unusual cases where custom settings gives better ratio for example BCJ on non exec files / files where BCJ2 custom settings for streams would be good, files for delta filter (so far I encountered usable settings: 1, 2, 3, 4, 6, 8, 12, 16, 24, 36), some hybrid text/binary files would be interesting too.
PM for "licensed" files.

PS.
I decided to merge my tools for 7z recompression and release it for public consumption...
