bed mesh: waved bed

Hi,
I have assembled my new vcore 3.1 400. But I'm running into some issue with the bed.
I admit I didn't follow the guide carefully and forgot to check the bed without heater and without the magnetic pei.
I started with a tilted bed, and I was able to get it lke the second screenshot.
I lowered/heightened the front beams.
In order to try and fix the wave patern on the y axis I also loostened the X and Y rails except the middle 2 screws and started tightening from the middle to the outsides.

Screenshots are with bed is at 80°C.

Is this somehow acceptable?
Any tips to improve?
Any explanation why the front seems to be to high? I thought z-tilt made sure the fronts are aways at 0.
