HCD.10:4.3 - Design Variation around a Warranted Change of Action

Choose a condition that can make the correct action differ: configuration FW7 versus FW8, 24 versus 22 test hours, 80 records versus 60 distinct requests after duplicates, pressure near 448 versus 400 kPa, complete versus missing source information, or a different authority or support boundary.

State the expected discrimination before the attempt. A useful variant can require a justified refusal, supported continuation, changed calculation, specific request, different Method, or preservation of the earlier action. A new story with the same values and answer is surface variety, not evidence-bearing variation.
