Having just begun what could be a long adventure with rye breads, I may not be an expert yet.  But I've developed a formula that replicates the texture of 40% rye dough.

800 g warm water

750 g rye sour

150 g quick set cement

50 g Epoxy

1/2 cup Altus (optional)

1 Tbsp Caraway seeds (optional)

Once you mix the ingredients (I recommend a mason's trowel) and scrape as much as you can off the spatulas, your hands, the bowl and the work surface, you have enough for a small dinner roll.
