Comparing the Beutler formula with D-23 is like trying to compare apples and oranges. D-23 is a solvent developer (lots of sulfite) while the Beutler formula is an acutance developer which works on the principle of having only a minimum of sulfite in the working solution. Even if you should dilute the D-23 1+3 the two developers will still work differently.
