An undiscussed topic about Maker

How are the costs of making High grade Dex Crystals affected by not bothering to assess the low-grades? I thought of this later...

Yeah, I had looked at that last night.
It invariably comes out cheaper to skip the low grades entirely because you're not reprocessing them twice... and at low volumes it makes no noticable improvement in your profit potention:

At high volumes it's not much better either:

The break even cost / profit margin is much better discarding lows entirely, but depending on how much highs actually go for they can turn a decent profit on thier own.
