I give one cup twice a day to both my 90 to 95 pound male ridgie & also to my 75 pound female mix.....both older.
However, my dogs also share 2/3 of a can of soft food each day, not to mention the treats.
So, the 4 or so cups per day might be right if that is all the food that she is getting. If Abi also gets soft plus treats then that might be too much.
Also, your girl is younger than my two & she will have a higher metabolism.
Best thing to do IMHO, is use the 4 cups as a baseline, adjust it down depending upon how much soft food & treats she is also getting & then monitor her weight & adjust accordingly.
