I think GP's point was also that the Swiss look middle-of-the-league only when comparing their strict definition (>3m is counted as a delay) with the looser definition used by other countries (>5m is counted as a delay). Presumably, if trains with a 4- or 5-minute delay were not counted as delayed, more than 92% of Swiss trains would be on time.
