I've taken a look at the Sotzmann article, a longer German work about Losbücher, which also reports about Fanti's work:
http://books.google.com/books?id=vLMEAA ... er&f=falseIt comes to 74 (!) astrologi and to 1628 answers (= 74x22), also he refers to two alternatives, either divination according "dice rolling" (21 possibilities) or according the "hour of the question" (which would then have 24 , or, if one block of 3 hours was reduced to 1, would have 22). Perhaps these alternative methods explain the difference in the final construction of the answers.

I counted. Indeed it are 74 (one page - Alazimini 2 is a double copy). The first "Atlante delli astrologi principe" sounds, as if it is not a "real astrolog" ...
... but then it would be 73 (which would fit somehow with 365 days for a year; 5x73 = 365). But each of the 74 units has 22 answers.
One is a an astrologa "Helisabeth Regina" ... it appears at the 50th place.
No. 6+8+10+12+14+16+18+20+22 + 28 + 40 are Sybils, totally 11 sybils
No. 6+8+10+12+14+16+18+20+22 is somehow similar to the pairing principle in the Boiardo Tarocchi poem (there are 2-4-6-8-10-12-14-16-18-20 and additionally 21 connected to women.
"22" (Tarot) + 28 (Montefeltro-system) + 40 (Minchiate) + 50 (Mantegna-Tarocchi) are system-numbers, which are known from other places.
It seems, that Fanti wished to express something with this form of sorting. "Atlante delli astrologi principe" would be a foolish element (0= Fool), 22 "Sybilla-Europa" would somehow express the function "World". Sybilla Amalthea reminds the foster-mother of Zeus. Sybilla Erithrea ... I don't know.
