All the metadata StatefulSets have requests.cpu set to 500m. Combined with a targetCPUUtilizationPercentage of 50 on the HPA, this meant that they'd try to keep an absolute CPU utilization of 250m = 500m * 0.5. Changed the CPU utilization on the HPA to 100, so now the absolute utilization is 500m = 500m * 1.0.
