 ### Pod-level Policies
 
-If the Pod-level policies (i.e. `pod.minAllowed` and `pod.maxAllowed`) are violated, the recommender and the admission controller should proportionally adjust the Pod-level recommendations:
-  * If the Pod-level recommendation is less than `pod.minAllowed`, use the minAllowed value as the new Pod-level recommendation.
-  * If the Pod-level recommendation is greater than `pod.maxAllowed`, use the maxAllowed value as the new Pod-level recommendation.

-The updater skips Pods for which no Pod-level recommendations exist in the corresponding VPA object. Consequently the updater may skip validating `pod.minAllowed` and `pod.maxAllowed` for such Pods.
