Try it find FAILSAFE methods? (ignored many srep errors during decompression.)

Trying use internal LZP compression faster than lzma and betterly compress, incompressibble data or use very strong compressors. Likely LOLZ or RAZOR. This two compressors very goodly compress hardly compressibble data than others. (avg. 0.5-1% to upto 2-3% or better.) Default srep settings = bigger results this sample file. Try l32-64 settings need more memory from biggest datasets and not guaranteed failsafe decompress, except minimally better ratio. MSC/BPK/OGGRE not enhance ratio/compress the data.

Few quick test results added in TXT-file. (zipped)
