The low contrast neg received HC-110 Dilution H, for 14 minutes, which was probably about 2 minutes too much. I would recommend 12 minutes.
For normal contrast I developed for 10 minutes using Dilution H, and high contrast 8 minutes. I normally don't cut development short for high contrast scenes, but the Foma films build contrast so quickly that highlights are quickly blocked up if proper care is not taken.
Hope that helps. It's a wonderful film with great texture, beautiful tonality, and a nice grain.
