I used this conversion sheet with good success some time ago for getting DS-10 sorted out. I thought it might prove useful for others.... It's simply the Massive Development Chart info for Xtol pasted into a calculating sheet side by side for DS-10. It gives the 20% time adjustment suggested for starting points with DS-10 and most films.
For those interested, this is the formula:
DS-10 1L
Dimezone S 0.15 g
Ascorbic Acid 8.0 g
Boric Acid 4.0 g
Salicylic Acid 1.0 g
Sodium Sulfite 75.0 g
Triethanolamine 10 ml
Water to 1000 ml
