Depends at my store.
Paper usually gets 6 or 7, but he also does plastics.
Chem gets anywhere from 5 to 8. It varies, but without any relationship to his freight for the day.
Personal care gets 6 normally, but she also sorts for beauty and fills in wherever.
OTC is typically 5 these days. Sometimes more if PC has the day off.
Infants gets 4, but she has limited availability for school and the TL does most of the work there.
Pets get 6 normally, but half of that is truck unload.
Those are just my observations based on when they typically leave.
