Necessary Evil Srep
 

From my research i have found that srep can e called necessary evil... I compressed a file with srep+arc:max and but got less size. but when i did it with 7zip, i got much size. I saw that most of the repack team use srep with low settings and lzma with high setting.

So to repack i use precomp+srep:m3f:a1+delta+exe+lzma:max

is it good?

hmm, yea, I guess but just check the outcome of the data you are compressing, like how long did it take, what was the final size, how long does it take to decompression and stuff like that then decide which compression method is best for you.
