Well for me,
5.33oz sammies(Large roll)= 50lbs cooked X2 for shrinkage= 100lbs Raw pork
4oz sammies(small hamburger bun) = 38.5lbs cooked X 2 for shrinkage = 77lbs raw
Personally I like the larger portion and price that way, Makes me look better and any leftovers go to the customer so they are super happy.
Good luck with the cook.
