Your reasoning is not correct. It really needs to be 1/14, because on average you need to do a repair after every 14th cash collection. This average is obtained from dividing a person's total number of cash collections by his total number of repairs. This yields a number close to 14 for everybody. So it is not the formula that made up the 1/14, it is the game that works that way.
