I was not suggesting replacing HQ with ascorbic acid in any formula. I've stated many times on here I do not believe in simple substitution formulas. Once something is changed, the entire formula needs to be looked at and possibly rebalanced, or scrapped.
Bob  the formula Gerald posted for the Haist version of D76 (D76H) is correct. The formula is the same as D76 except the HQ is eliminated and the Metol is increased to 2.5g. Image characteristics are said to be virtually identical. As for its capacity compared to regular D76, I cannot say.
