As promised...... in my experience, dried dates will give you 26 points per pound per gallon (1.026 specific gravity). Sorry that's all I know. I would guess the other dried fruits should give very similar results.
EDIT: Now I'm wondering if the Experimental Homebrewing book assumes the dried fruits are sugar coated?? Hmm, my scientific mind will think on this some more............
EDIT #2: No, I'm right. EH is wrong (sorry Denny). Dates should give about 26 ppppg based on my experience. The ones I used were not mashed with any malts, just crushed and added to water, then measured with hydrometer. If mashed with malts, they would have yielded more, as carbs got converted to more sugars.
I calculate figs might be as much as 32 ppppg if mashed with malts and assuming 100% efficiency. Otherwise assume a bit less. Raisins the most, up to 35 ppppg, same caveat. This is based on the nutrition information from real dried fruits in my kitchen cupboard, ratio of grams of carbs per total grams, and assuming it's all converted into sucrose, which it's actually not, but anyway, sucrose has 45 ppppg, so... you probably ain't going to ever see the 1.070s for one pound in one gallon that EH talks about, not sure how that would happen?!?!
