I’m a member of a cricket club and play the game often. No one watches the ball each second TBF. Its all over by the time your stumps are smashed. From batter to bowler its < 1s We are ‘aware’ of speed so when we receive a 75mph ball (we cant get to international standard speeds) you get a sense of the ball coming at you at motorway car speed. Similarly there are spin bowlers who bowl [sometimes half that speed] much slower but are hard to hit. ITs just something we’re use to. The speed metric (excuse the pun) of mph is just something extremely familiar and is a big part of the game. Metric countries would be familiar with what a 130 km/h ball ‘feels’ like.
We have a bowling machine where you set the speed before you release balls in to it. As yet no-one has complained about the ‘hour’ bit being difficult to judge due to time and some of the younger members are highly numerate. We just associate it with something familiar as we stand as a target for the ball. > On 5 Aug 2021, at 2:41 pm, Brian White <[email protected]> wrote: > > Your friend. > >> On Aug 5, 2021, at 02:11, [email protected] wrote: >> >> Those who are innumerate yes.
