Oracle Advanced Compression Advisor

Hi

We are running the advanced compression advisor on a 11.1.0.7 database and the  advised compression ratio is 1.89.  Does this mean that with compression turned on approx 1.89 blocks wll used 1 block. Have tried trawling through documentation but have found no clear definition for this ratio

thanks

Paul
