   That said, there are a few edge cases where it can be desirable:
 
-    @li To improve performance for particular scenarios
     @li To allow adjacent records to be viewed directly in the dataset
-    @li To reduce dataset size (eg when there are deleted records)
+    @li To apply compression, or to remove deleted records
+    @li To improve performance for specific queries
 
   This macro will only work for BASE (V9) engine libraries.  It works by
