Why I did it:
I thought it would be valuable as part of the Susemai Ink Testing. Susemai instructs dilution to a 2% to 8% concentration, this lets you see the implications of the percentage you choose.
Why you might recreate any of these mixes:
This ink became available for sale and you are mixing it up.
This ink should really be marketed as a grey. It was way too wet at the recommended dilutions despite being having a nice black color. However, it also makes a nice grey and the surfactant becomes dilute enough for it to be usable.
I am waiving my general disclaimer about mixing with water, because this ink is intended to be mixed up with water for most of the posted dilution range.
