I am suffering from high utilisation in the evening when my download speed drops from 100mbit to 28mbit, when this happens i notice that part of my upstream power levels are different on each channel when i believe they're normally the same.

For example my current power levels are 39.75, 39.75 after a reboot which i think looks normal but last night they were reading 40.25, 41.75.

What is the significance of the numbers being different after the decimal point as i thought the reason was mentioned here by someone but i can't find the post?
