Help! To properly configure "pLZ4" to have a good compression in bf4

[poker2332]

Hello and thank you all for reading this post.
For some time now I am wanting to make a repack of bf4 premium edition ... The problem is that I can hardly reduce its weight.
The complete game with all its dlc weighs 68.6 GB but after the compression its weight is 42.8 GB.
What am I doing wrong?
There is a repack of the same game ... with a total weight of 29.3GB.











method
pLZ4+srep64+xz

ARC.INI

[External compressor: pLZ4]
header = 0
packcmd = pLZ4 e -l9 -t8 -st100p -ct16 -c64m - -o - <stdin> <stdout>
unpackcmd = pLZ4 d -t8 - -o - <stdin> <stdout>

[External compressor:srep64]
header = 0
packcmd = srep64 {options} -m5f -d1g -a2 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep64 -d -s - - <stdin> <stdout>

[External compressor:xz]
header = 0
packcmd = 7z a -txz -an -mcrc=0 -m1=lzma2:d25:fb=273:mf=bt4:mc=1000000:lc=4:lp=0 -mmt=4 -mx9 -si -so <stdin> <stdout>
unpackcmd = 7z x -txz -an -y -si -so <stdin> <stdout>
