VC4 500

Hello, I'm currently adjusting my VC4 500 Hybrid. So far everything has gone well and I have installed the hybrid y belts, now I have arrived at the input shaper. I just can't do much with the measurement, i.e. I have no idea what it is telling me. Not even after hours of reading here in the discord. Can anyone tell me why i have a 2nd spike on y?
