 The current target value on the Horizontal Pod Autoscaler (HPA) often does not match with the metrics on the system you are scaling on. This is because of how the Horizontal Pod Autoscaler's (HPA) [scaling algorithm](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/#algorithm-details) works.
 
-By default, KEDA scalers use average metrics (the `AverageValue` metric type). This means that the HPA will use the average value of the metric between the total amount of pods. As of KEDA v2.7, ScaledObjects also support the `Value` metric type. You can learn more about it [here](/docs/latest/concepts/scaling-deployments/#triggers).
