A bit of a rub with the examples. Baldness isn't a binary condition, it's a continuous set of outcomes, ie levels of baldness. Same with the heap of sand. There's no definite number of grains, but it's reasonable to say a heap occurs once the sand cannot pile higher without getting wider. Football catches are binary outcomes. There are no "mostly caught" (like mostly bald) cases. Either it was or it wasn't. But like with the sand, it's hard to put a number on each of the variables. Time of control, amount of wiggle, number of steps etc.
