Improvement and Scope

Final minus First-Pass

The final lesson before the boundary computes the exact yield difference.

highlighted = computed this step

Compare yields

The final yield is compared with first-pass yield.

improvement=final yield−first-pass yield\text{improvement}=\text{final yield}-\text{first-pass yield}

Improvement

The difference is 3/20.

19/20−4/5=3/2019/20 - 4/5 = 3/20
