This is an important point. The TD formula is a 'D-23 variant + alkali B bath' formula, not a true divided formula.

Reducing the sulfite in bath A to say 50g might increase "sharpness" slightly (actually sharpness will be little affected but graininess would increase slightly which may give make things appear a little sharper). Time/agitation in bath A could be extended to compensate for any lost contrast. This would be a similar adjustment to the Dalzell modification of Stoeckler's.

Alternatively, the pH of bath B could be increased, and the time in bath B shortened. The faster development in bath B would mean less solvent effect.

Experimentation would be required in any case.
