Getting tired of these massive swings in I-RoR

Anyone know why my I-RoR (orange line) sometimes looks like this? I look at other people’s RoasTime curves and rarely see swings this extreme.

It doesn’t happen on every roast, but probably every second or third one. Even when the machine has just been cleaned, and yes the I-RoR sensor as well. It’s wildly unpredictable.

Is this a sensor issue, something with the IBTS readings, or something else entirely? Curious if other Bullet users have experienced this and figured out the cause. I am getting sick of watching my I-RoR sky rocket and crash all over the place…I usually rely on bean sensor when it happens but for a machine this expensive it seems kind of ridiculous to have to deal with.
