Developers are formulated for film speed, sharpness, or fine grain. No developer optimizes more than one. I can mix D76 from scratch in one liter batches and it lasts 6 months decanted into eight 4 oz bottles. Dilute 1:1 for use.
It is a nice middle of the road developer that does not optimize any feature. I have yet to fine a film that is not at least good in it except the new /current formulation of Delta 400, 100 is just fine. For 400 use Extol or Ilford equivalent liquid and it is superb. I have a thing against premixed liquids when they code the dates so you can not read them. Really bad when it does not go off color when bad like DD-X, but if fresh it is wonderful.
