On the contrary, they may be slightly overdeveloped, since as you mention, they are properly exposed (there is shadow detail where I want it) but the highlights are too dense. I used the 13.5 minutes someone mentioned as a starting point but reduced is to 13 minutes since I use a Jobo. Next time I will try even less time, 12.5 or even 12 minutes. In general, I find that I need to reduce the times given in the film data sheets to compensate for the continuous agitation. For example, my time for Delta 100 is 15 minutes, and for Fuji Acros 13.5 to 14 minutes, both in XTOL 1+3 at 20C. Both of these times are shorter than what the data sheets suggest. Also keep in mind that my negatives are primarily destined for scanning. And since the scanner (in my case LS-2000) has more difficulty coping with very dense film (i.e. shadows in slides and highlights in negatives), this calls for less development in the case of negatives and more generous exposure in the case of slides.
