+    Size of the recovered Favicons database relative to the original corrupt
+    database.  Recovery is VACUUM-like, so the resulting database should always
+    be smaller.  Substantial 100% results would indicate empty databases being
+    recovered, substantial low% results would indicate very little data being
+    recovered.
