 Some groups may be created automatically by an implementation for the convenience of the user. Examples of such groups include
 a group of nodes assigned to a job or a group of objects being cooled by a CDU object. An implementation may choose to provide
-a group (or groups) of redundancy for CDU overlap where failures in a single CDU can be compensated for by other existing CDUs.
+a group (or groups) to represent which CDUs overlap so that failures in a single CDU can be compensated for by other existing CDUs.
 Having such redundancy groups provides opportunities for users to determine if CDU failures can be compensated for by adjusting
 existing CDU capacity or if they require other actions to ameliorate.
