Vcore4 500 IDEX: Layer Shifts & Y Belt Tensioning

Does anyone know where i can find a graph on the Hybrid belts (Y-Belts) and how to tune it and what an acceptable input shaping graph should look like as well? My graph doesn't seem to be too kind and I am a bit confused as to how to generalize an acceptable range.
When printing with a single toolhead (Toolhead T0), I get massive layer shifts on the print as well. Looking forward to your responses. Thank you!
