    Again, i think bcj2 is really not helping here.

    test.7z is bcj2 filtered/stored
    test1.7z is stored
    There are 710373298 bytes of exe in vm.dll

    Edit:
    file used for testing is
    paq8pxd_v10.exe

    Code:
    
    paq8pxd_v10 -8  test.7z
    Creating archive test.7z.paq8pxd10 with 1 file(s)...
    
    1/1  Filename: test.7z (354766 bytes)
    Block segmentation:
     0           | default   |    354766 b [0 - 354765]
    Compressed from 354766 to 93606 bytes.

    New record is coming

    Code:
    1. precomp 0.4.3 -progonly+ -intense -cn   5 188 081 467
    2. reflate (optimal level for every raw)   7 055 933 089
    3. srep 3.92 x64 -m5                       3 756 906 254
    4. paq8pxd_v10 -8                            570 377 158
    This is 3.0% better than my previous personal result. But only 0.3% better than Edison007's result. Honestly speaking I expected a bigger gap.
    Also here are the results with delta filter before and after srep.
    Code:
    delta+srep    572 915 135
    srep+delta    572 771 214

    pretty obvious, paq contains better own filters than those delta/bcj2
