Can't work out what this peak is

I have this peak when testing the belts. Nothing along the belt path is binding I just can't work out what it could be. Running ebb42. Switched to a completely different toolhead assembly and it's still present.

Your belt graphs look pretty good to me to be honest

They say you shouldn't mind peak height differences on the belt tension graph. I'm just wondering what it means. As for resonances, they are really good, just stop there.
