Bed Mesh taco with some obvious inflection from alignment

Rebuilding a used Rat Rig 300 that the prior owner never quite got to work right. And I'm new to Rat Rigs, which isn't making this easier. These graphs were taken at room temp because I'd like to get a baseline in before I start introducing heat to the alignment.

Looking at the range of 0,0 to 300,0, with the little twists up and down at the end, and then the plate in the 300,300 tilting down, it's obviously I have some squaring to fix. But frankly, it seems like the things I'm trying are not really doing much. Like, I get the discrete feeling the rear Z axis isn't fully aligned, and that's what causing the twist, but I'd like to see if anyone else has any better ideas, as I think there's telltale signs that more knowledgeable people might be able to spot.
