Take the following as truth: At best, experience with different combinations of waist sizes and leg lengths for a given design allows a scheduler to aggregate the units to be made into groups of large and small sizes, which means marker-makers can achieve efficiencies near 90 percent for casual pants.
Then the following statement: "Makrer-makers can only ever achieve efficiencies of 80 percent for casual pants." is true, false, or inconclusive?
Answer: False
