Failed bottom-side bleed through solutions

Lately, I've been focused on trying to solve my bottom-side bleed through. I still have not solved the issue, but I'm making a list of what hasn't worked for me.

1. Changing to a darker color (red to black)
2. Adding pigment to the resin, (granted, I tripled the pigment in my ignorance)
3. Continuous printing to the first 3 bottom layers
4. Not dipping the first 3 bottom side layers

Curiously, the bottom layer of my pigment test shape deformed like a ceiling patio shade suspended on posts, with the posts being the support nails. That layer is very slowly moved down for the next layer, so hydrodynamics are not deforming the layer. My current hypothesis is resin shrinkage deforms the bottom layer.

The following pictures are of the bottom layer of the object.

 Standard dip method, only the color changed

Continuously printed dice to the first 3 bottom layers, then standard dip method

First 3 layers were not dipped, but simply moved down for the next layer

Standard dipped wedge

First 3 bottom layers were not dipped, just moved down for the next layer

On a side note, in trying to fix the issue I have implemented continuous printing for the nail supports, which helps to shorten the printing time, and then dip the remaining layers for the actual object.
