Measure actual time consumed by each system component before
Measure actual time consumed by each system component before optimizing, because subjective experience of difficulty does not correlate reliably with objective constraint status.
Why This Is a Principle
Grounded in Memory is reconstructive, not reproductive—humans rebuild… (memory of duration is biased), Bias Blind Spot Asymmetry (bias blind spot), and Systematic Overconfidence Taxonomy (overconfidence). This prescribes measurement before action based on axioms about unreliable subjective assessment.
