Wandering z-offset (self.3dprinting)

I've got an Ender 3-pro with cr-touch and plastic washers instead of springs. I sanded down the washers to manually level the bed to var of 0.372.

When I adjust the z-offset it prints great but I need to adjust it before every single print. It stays within a fairly narrow range, -1.11 to -1.37 but if I don't do that adjustment, the print usually fails.

I preheat the bed and nozel before adjusting it. None of the screws seem to be loose. The nozel doesn't jiggle around. I tightened down the screws for the z-actuator.

What else could I be missing?

Why plastic washers instead of springs? Is the bed sagging due to the washers deforming with heat?
