I'll try to explain , use a winch as an example , if you put a larger gear in place of the the small gear ,you can retrieve the load faster but it takes more effort......or look at it this way , whenever you decrease travel you increase effort , short lever , increase effort , long lever , decrease effort , gears are" round levers" ...
You can buy a Schroeder steering box w an 8:1 ratio , but you better have some arms and be willing to stay "up on the wheel" on the street , there'd be no forgiveness at all .
