MS73 layer models might be overfitting

I can best explain this with a scenario:

I did a Pixel run with folio 023. I then produced models with that run and used those to do a second Pixel run with folio 017. Those latest models could separate folio 017 fairly well. I then did a third Pixel run with folio 260. Those models separated folio 260 perfectly, but when they tried to separate 017 they produced three almost completely empty layers.

This has been happening fairly often; models we make do a great job separating the folio they were just trained on, but can't separate any other folio, including ones they were trained on previously.

These are the models I'm talking about:

@kyrieb-ekat did I explain that right
