Backup compression level - Difference between CMP and compressionlevel?

Hello,

I don't understand the difference between this 2 settings. The compressionslevel settings are also unclear. In your PDF stand values from 0-9 for the compressionslevel, but Paragon use 0 for "non compression", 1 for "min compression", 2 for "max compression" and 10 (?!) for "normal compression" (in the .psl).

I hope someone can help me.

Thanks,
