I think I must have been 3 or 4 years old when I fully got the concept that even 3 out of 10 is better than 0 out of 10, and worth doing. Then maybe somewhat later but still not recently when I got the similar concept that even if you need all 10 components of a system before you get the payoff, you still have to build up the individual bricks one at a time if you ever even want a chance at maybe getting all 10. Even in a security context where on one hand it's true that the tiniest pinhole is all it takes, it's also true that there is no such thing a no pinholes, and yes, 80% coverage, even 10% coverage, is better than 0% coverage. It's a goal and an ideal not an absolute.
