NOC VIEW and refresh timer

Is there a trick to getting utilization updates when using interface gauges and NOC VIEW MODE?

I've created three tabs with different gauges on each screen. I made this with Custom HTML to where each is the same format/size etc

But as they cycle in Noc Mode they don't get updated based on the NOC cycle timer (15 sec.) nor from the web page refresh timer (5 min.).

However, I left these running overnight and saw that at some time during those hours it actually did refresh the utilization gauges and updated.

Any ideas how to make this update faster?
