Run a comparison that means something

Ask the same question, open every citation and record which evidence supports the answer.

  1. Keep your input, instructions and required deliverable consistent.
  2. Record errors, omissions and the time spent making each output usable.
  3. Check whether the result exports into your actual working environment.
  4. Compare the current plan and data terms required for that task.

Make your own call
