It appears you're using the term "compression ratio" to mean "size
reduction". A compression ratio is the ratio (compressed /
uncompressed). A 1 kB file compressed with a 10% compression ratio
would be 0.1 kB. It seems you're using (1 -
compressed/uncompressed), meaning that the compressed file would
be 0.9 kB.
