I think the first sentence of the chapter "Example" is wrong.
In one study, participants were asked to judge which of two road improvement plans would be more efficient in reducing mean journey time. Respondents preferred a plan that would increase the mean speed from 70 to 110 km/h (43 to 68 mph) more than a plan that would increase the mean speed from 30 to 40 km/h (19 to 25 mph), although the latter actually saves more time.
From 70 to 110 km/h you will save 36% of your time From 30 to 40 km/h you will save only 25% of your time 94.36.116.147 (talk) 14:58, 22 November 2022 (UTC)
