EDIT: You should try srep+zstd and zstd should be set at level 19, download the latest zstd from my attachment and use cmdinfo by felice for the info about the use of it

I tested level 19 However it took much time to complete a single 400 MB File & still srep+lzma better in ratio & speed

Did you compared using srep+zstd or just zstd, try with srep+zstd if you didn't done that!

yes i did that
72,966,144 => 28,393,926 bytes. Ratio 38.9% srep+Zstd [level 19]
72,966,144 => 24,839,507 bytes. Ratio 34.0% srep+lzma [max]

I tested on link file from DOA5LR

Bro, if you see other settings of zstd and configs, then zstd could make compression same or even less in most condition, there chunk size also matter, like for lzma, you set it for max but in zstd, u used simple way, and that why 4mb difference you see!
