Of note is the `HRA.spec.scaleUpTriggers[].duration` attribute. This attribute is used to calculate if the replica number added via the trigger is expired or not. On each reconciliation loop, the controller sums up all the non-expiring replica numbers from previous scale-up triggers. It then compares the summed desired replica number against the current replica number. If the summed desired replica number > the current number then it means the replica count needs to scale up.

As mentioned previously, the `scaleDownDelaySecondsAfterScaleOut` property has the final say still. If the latest scale-up time + the anti-flapping duration is later than the current time, it doesn’t immediately scale up and instead retries the calculation again later to see if it needs to scale yet.
