I live in Chicago and the consulate's jure sanguinis pdf is here:

There are 5 categories that detail the documents you need to prove your eligibility.
This is category #5:
My paternal great-grandfather was born in Italy in 1891.Category n. 5:
Paternal or maternal grandfather born in the United States, paternal or maternal great grandfather born in Italy:
Italian citizen at the time of your paternal or maternal grandfather’s birth.
1. PATERNAL/MATERNAL GREAT GRANDFATHER’S BIRTH CERTIFICATE, from Italy;
2. PATERNAL/MATERNAL GREAT GRANDMOTHER’S BIRTH CERTIFICATE;
3. PATERNAL/MATERNAL GREAT GRANDPARENTS’ MARRIAGE AND DEATH CERTIFICATE;
4. PATERNAL/MATERNAL GREAT GRANDFATHER’S CERTIFICATE OF NATURALIZATION;
If the above document is not available, please see all the information in “THE USA NATURALIZATION”;
5. PATERNAL/MATERNAL GRANDFATHER’S AND GRANDMOTHER’S BIRTH/MARRIAGE CERTIFICATE AND DEATH
CERTIFICATE (IF APPLICABLE);
6. FATHER’S AND MOTHER’S BIRTH/MARRIAGE CERTIFICATE AND DEATH CERTIFICATE (IF AVAILABLE).
REMINDER: IF YOUR PATERNAL/MATERNAL GREAT GRANDFATHER BECAME A NATURALIZED U.S. CITIZEN BEFORE YOUR
PATERNAL/MATERNAL GRANDFATHER’S BIRTH, YOU ARE NOT ENTITLED TO ITALIAN CITIZENSHIP (unless you fit into
another category).
My paternal grandmother was born in the US in 1923.
My great-grandfather naturalized in 1937.
My father was born in the US in 1955.
I was born in the 1980s.
I was under the impression from my research that I was eligible through my grandmother because my father was born after 1948. Category #5 is very clear about eligibility through a grandfather, though. Am I wrong?
