I'm a PA in a PFresh store and have done it twice. To me I think it would depend on how your store is setup. We do it with 3 people..
1 does meat cooler, 1 starts produce cooler, the other does the ambient room, once done with the ambient room they move to produce and and start at the opposite end of where the starting team member started..
Afterwards we all blitz the freezer because it sucks so much. in the two times I have done it, we got all coolers done in about an hour, and then we had to wait to do the sale floor which probably took 15-20 minutes. We also had barely, if any, audits.
