"After all, facts are facts, and although we may quote one to another with a chuckle the words of the Wise Statesman, 'Lies--damned lies--and statistics,' still there are some easy figures the simplest must understand, and the astutest cannot wriggle out of." Leonard Henry Courtney, 1895

tl;dr

Measurement is highly specific -- the time taken for this benchmark task, by this toy program, with this programming language implementation, with these options, on this computer, with these workloads.

Same toy program, same computer, same workload -- but much slower.

Measurement is not prophesy.
