+Lziprecover is usually able to repair files with small errors (up to one
+byte error per member). The error may be located anywhere in the file
+except in the header (first 6 bytes of each member) or in the 'Member
+size' field of the trailer (last 8 bytes of each member).  This makes
+lzip files resistant to bit-flip, one of the most common forms of data
 corruption.
 
    Bit-flip happens when one bit in the file is changed from 0 to 1 or
 vice versa. It may be caused by bad RAM or even by natural radiation. I
 have seen a case of bit-flip in a file stored in an USB flash drive.
 
+   Repairing a file can take some time. Small files or files with the
+error located near the beginning can be repaired in a few seconds. But
+repairing a large file compressed with a large dictionary size and with
+the error located far from the beginning, can take hours.
+
+   On the other hand, errors located near the beginning of the file
+cause much more loss of data than errors located near the end. So
+lziprecover repairs more efficiently the worst errors.
