Just did my first scan, how to adjust?

I wanted to scan my bed before attaching the heater and print sheet, now it's done and it seams like I need to tweak something 🙂 What do I need todo and how much? (VCore 400)

0,0 corner being raised, will automatically lower the 400,400 corner. then lower the 0,400 (right front) will raise the 0,400 corner (left rear) Split the difference in the readings between opposite corners on how high/lo to move that corner. A spare corner bracket, bolted to the vertical frame rail, and a nut and bolt can be used as a 'jack' and or reference mark as to how far you are moving the Y rail extrusion up/dn

So I'm adjusting the extrusion that hold the Y-rails, nothing else?

I re-scanned with the bed at 60c (did a PID-tune just before so it was well soaked). How does this look? Also this is with the PEI sheet installed.
