There have been several requests for DAE to include grind settings for each density.

There are several problems with this.

1. Different espresso basket diameters have different coffee bed depths, which requires different grind settings. For example a standard 58mm basket will require a much finer grind than a 45mm holding the same amount of coffee. You could apply a factor once you have figured out the difference.
2. There is no standard for grind settings between vendors. Its not like it is a setting based on microns. One vendors number range will be meaningless using a different grinder.
3. Worse, many grinders are not factory set at zero. For example my 1Zpresso JX-Pro grinder warned of this fact. The numbers may not match even an identical model grinder from the same vendor. You may be able to zero the grinder yourself. 

I do have a Kinu m47 Classic grinder, it is factory set at zero, and I have modelled the grind settings for a Flair Pro 2 45.5mm basket. These grind settings are provided below if you really want to try them.

I use these as an initial setting only during dialling in. I’m usually very close by the second shot, and pretty much bang on by the 3rd. However the grind will change as the coffee ages, and can change even with the weather.
