CAN bus utilization very spikey

My team attended Centennial College over the weekend and consistently saw extremely spikey CAN bus utilization.

Our robot has 10 spark maxes and we’re using AdvantageKit, so we are definitely querying a lot of information over the CAN bus, but I understand that this level of spikiness is still unusual.

We’ve already gone over all of our CAN connections to make sure we don’t have a loose wire somewhere.

Does anyone have any ideas as to what might be causing this issue?

AdvantageKit’s polling of the CAN utilization metric on the robot side causes this. It’s a sampling artifact, not actual utilization spikes.
