V-core 300 bed mesh

Hello i'm having a normal configuration of the bed mesh deformation. Mine is similar to the 3rd example shown in this video. https://youtu.be/h7ZTq2dDTkM I tried to loosen up the 2020 linear rail but it didn't change. What can be done to improve this mesh ? Thanks πŸ˜‰

Lets focus on the first one, you have got a saddle for the most part, so your first step would be fixing th X gantry I suggest unscrewing the rail and the screwing it just enough, and using every third bolt. That should eliviate the pressure and make it more consistent Then do a cold mesh again
