A comparison needs a common task
Your objectiveRecognize an unfair performance comparison.
Understand the idea.
Two results can differ because the systems differ, because the tasks differ or because the measurement method differs. A useful comparison keeps important conditions consistent and names the conditions that cannot be matched. A single score is not a substitute for that description.
A worked example.
System A processes short requests while System B processes long documents. Their response times are reported side by side without explaining the input difference. The chart may be accurate as a record of two runs but misleading as a claim about relative speed.
Try the reasoning.
Design a three-case comparison using the same input set and acceptance criteria. Include one difficult case rather than only the easiest successful example.
Carry it into practice.
Record inputs, versions, conditions and failure handling alongside the scores.
