How to change cadvisor metrics refresh rate?

I am working with k8s v1.13.2 scraping CPU and memory stats for some of my application’s pods from the kubelet/cadvisor endpoint /stats/summary in order to do some internal load balancing. It works fine but the refresh rate of the endpoint is very slow on the order of 10-15 seconds which makes the stats stale for quick running workloads. I haven’t been able to find a tunable to change the frequency that the stats are updated in kubernetes. Can anyone suggest how to do this? Thanks!
