Need advise on how to fix this mesh

So I think I am almost there with my mesh. There is this bow upwards in the front. I redid my gantry rail, but I guess that was not the problem. Anyone have any ideas? is it a frame problem?

Bed or frame?

Does this look like a frame or a bed issue? It's a 330x330 5mm aluminium bed with a textured PEI magnetic surface. It looked fairly straight until I had to replace the heater. Measured with a SuperPINDA.

Temperature for mesh and z-offset

Since I still somehow have strange problems with my first layers being off randomly I wanted to ask at what temp the bed and z-offset should be done. So far I do both at roomtemp which seems wrong, but doing them at higher temps gives me even worse first layers. I don't do a mesh before each print but manually from time to time since the mesh takes forever at the start of every print....

Clarifications about Frame Squaring Video?

I'm looking at squaring up a V-Core 3 400mm frame that is about .65mm out of square, and I'd like to double check a few things about 3d Printers & a Whiteboard's video about squaring (https://www.youtube.com/watch?v=h7ZTq2dDTkM) It sounds like for just a tilted bed mesh, the A/B points (the X axis in the front) is generally always going to have the actual corners defining one plane (since this is where the two points of the bed triangle are?) It sounds like corners D and C are hard to adjust, so generally you're just adjusting the Bar [AD] and Bar [BC], except we do it on the A/B ends of the bar due to D and C....

V-Minion Bed Mesh question

So I’m curious as to what a “good variance” would be for a machine of this size. I’ve been at it for a while today and the best I can get is a .091 mm variance. This is down from .455mm. Is it safe to stop here or should I keep on trying to improve it?
