What this video covers
We don't judge an experience by averaging every moment of it. We remember it mostly by two points - how it felt at its most intense (the peak) and how it felt at the end - and we quietly discount how long it lasted.
One wait was longer than the other, yet you'd rather repeat it - because it ended well, while the short one ended sour. You didn't tally the minutes; you remembered the peak and the finish. That's the peak-end rule, with the duration and all the dull bits neglected.
