What is the reason for 15 30 40 in tennis?
Tennis scores were shown in the middle ages on two clock faces which went from 0 to 60. On each score the pointer moved round a quarter from 0 to 15, 30, 45 and a win on 60. Somehow the forty five got truncated to forty when the clock faces dropped out of use.
