Could you please interpret my IRQ balance results?

I'm using a router with this hardware, IRQ Balance is active and configured, my router has been on for about 3 hours and the error count is only 3. Do you think these settings are using IRQ Balance and the system CPU in the smartest way possible?

Looks like its about as balanced as is possible

This is how the most balanced results I could get on this device

Do you have any advice?

Your results look well balanced. No need to do anything.

Main thing is to get the Lan, wan, WiFi distributed to different cores, and you seem to have that.

Thank you very much for your help.
