I can't get my bed level at all

I've been printing with my Prusa for a few months now but also had some issues getting that perfect first layer. I used a few tricks I found online, like a larger first layer, slowing the speed down, and pushing out more plastic. This can work, but it's not perfect. So I decided to dive deep into figuring out the perfect first layer.

That all being said, I'm really unable to print much at all now. I just discovered the Bed Level Analyzer plugin, so here's a picture of my mesh:

I've been running the bed level test from Prusa, probably dozens of times over the last week, and none of them come out perfect, even with the bed level correction in the software.

I have tried adjusting the bed screws to all the same tension, but that doesn't seem to help. Right now I've get them all screwed in quite tight, is that how it should be?

With the Pinda sensor, I figured it would compensate for physically raising and lowering the bed, and it seems to, but it still always off. Specifically the bottom right corner is too low, while the middle left is too high. Adjusting the bed level in software isn't enough for how bad these issues are.

Any suggestions or links to resources would be greatly appreciated!
